How many powers of x y on a math book are played?

Press the "alt" key and don't put it, then press the number key on the right (the light of the number key must be on, if it is not on, press the "numlock" key before pressing the "alt" key, and then let go), after the light is on, press the three numbers of 178, and then release the "alt" key, and it will be typed , squared.

Press the "alt" key and don't let go, then press the number key on the right (the light of the number key must be on, if it is not on, press the "numlock" key before pressing the "alt" key, and then let go), after the light is on, press the three numbers of 179, and then release the "alt" key, and it will hit , cube.

The rest doesn't seem to be able to be typed.,You can use to represent,When you play,You don't use any input method.,Just press the "shift" key and don't put it.,Then press the top of the letter key on a line of number keys 6,Then let go of the "shifr" key.,Then enter the number (how many times) you can.。 ^_

Don't copy the following!!

When asking a question in Know, some superscripts cannot be entered.

Generally, the nth power of x is used to be represented by x n, for example, x 4 is the 4th power of x.

For some special superscripts, the input method is as follows:

Square: Hold down the alt key without entering, then press 178 on the keypad in turn, and release the alt cube after pressing: the steps are the same as above, the difference is that when you press the number keys, it is 179 angle: the steps are the same, press 176

Plus or minus: Press 177

In addition, the multiplication sign is 215 and the division sign is 247

That's all I know

No, on the computer you play"shift"+"6"The character will come out, which means how many powers, and this symbol can also be seen on some calculators.

You open the word document, open "Insert" - object "- what time is the formula". Or, turn it on.

Format" - font "- superscript".

In word, select the text you want to use as a superscript or subscript, right-click on it, select "Font", and then select "Superscript" in "Effect".

For example, if you want to enter x to the 2nd power, enter x2 first, and then select 2 to perform the above operation.

Do not open the input method.

Press shift first, hold and hold.

Then press the number 6 on the letter

That's it.

Find a formulator mathtype, all kinds of mathematical symbols are exhausted, and some formulas can use the upper and lower subscript method on the first floor.

When x=1, y=1, the dot bucket contains a(1,1), y=2, and the reedin hole k=y |1 = 2, y 1 = 2 (x 1) that is, the tangent equation is 2x - y - 1 = o, because the tangent of the curve at a certain point is perpendicular to the normal, so the slope of the normal is a 1 2, y a 1 = a 1 2 ( a 1), that is, ten 2 y a 3 = o.

The tangent equation at =1 is 2 y-1=o, and the normal equation is 102y-3=o. The value of the derivative of the curve at a point is the slope of the curve's tangent at that point.

Hello! Glad you asked!

One x one y) xy (x y) xy

Answer: One x one y divided by xy and other bright answers are carried in (x respectful y) xy.

Yours is the greatest support to me! Break a leg! Thank you!

∵√x-3≥0，√3-x≥0

x-3=3-x

x=3∴y=2

x y=9 This is the conclusion I came to after meditating on it, if it can help you, I hope you will give me one (satisfaction).

If you can't ask, I'll do my best to help you out

It is not easy to answer the question, if you are dissatisfied, please understand

Root number x-3 0, root number 3-x 0, x-3 0, 3-x 0 x-3=0, 3-x=0

x=3 y=x-3 under the root number plus 3-x under the root number plus 2 (will not be rooted) = 2

x to the y power = 3 to the 2nd power = 9

This is the proportional series, and the common ratio is 1 x

So. y/x+y/x^2+y/x^3+..y/x^10y/x(1-(1/x)^11)/(1-1/x)y(1-(1/x)^11)/(x-1)

Agree. Whistleblowing |17 minutes ago zssasa1991 |The seventh level is the proportional series, and the common ratio is 1 x

So. y/x+y/x^2+y/x^3+..y/x^10y/x(1-(1/x)^11)/(1-1/x)y(1-(1/x)^11)/(x-1)

Friend, do you know the MATLAB numerical calculation program? If you can, first convert the denominator of the original question into the tenth power of x, and then merge them together, and then use Qin Jiushao's numerical calculation method, which is very simple! Just enter the value of x,y and you will find the solution in no time!

Thank you and good luck!!
