Anonymous users2024-02-16A minus 5 power of 10 is equal to.
The operation of finding the product of n identical factors is called the power, and the result of the power is called power. where A is called the base number and N is called the exponent. When a is seen as the result of the nth power of a, it can also be read as "to the nth power of a" or "to the nth power of a".
A number can be regarded as its own primary square, and the index 1 is usually omitted. Put parentheses when writing fractions and negative numbers to the nth power. The four operation sequences: multiply first, then brackets (first small brackets, then middle brackets, and finally curly braces), multiplication and division, and tail addition and subtraction.
Calculate a number to the decimal power, and if that decimal is a rational number, take it into the form of (i.e., fraction). In particular, the power of non-positive exponents equal to the power of 0 of any number other than 0 is meaningless.

Anonymous users2024-02-15First of all, let me explain the negative power.
How did it come about. Same as base.
Mi knows, right? It is two numbers with the same base number and different exponents, if the two numbers are multiplied, the base number remains unchanged, and the exponents are added, such as 3 2 3 3 = 3 (2+3) = 3 5. If the two numbers are divided, the base number remains the same and the exponent is subtracted.
For example, 3 3 3 2 = 3 (3-2) = 3 1. Then a negative exponent (to the negative power) is when the exponent is negative. 3^2÷3^3=3^(-1)=1/3。
Everything else is the same. At the end of the day, a (-b) = 1 (a b). Then your problem, 10 (-2) can be solved, =1 (10 2)=1 100, 5 (-5)=1 (5 5)=1 3125
Hope it helps.

Anonymous users2024-02-14At 25, the ion product of water kw = [h] [oh-] = 1 10-7 = 1 10 7 = 1 10-14.
Since water absorbs a lot of heat during dissociation, the temperature increases, and the degree of water dissociation and kw also increases.

Anonymous users2024-02-13No. Orders of magnitude rounding require rounding down, i.e., taking the largest integer that is not greater than the current index.
In this problem, the largest integer that is not greater than is -6, so its order of magnitude is -6 power.
If mine is helpful to you, welcome!

Solution: 10 (-5) = (1 10) 5
If there are any questions that won't be asked to me directly in the future, I don't want your points... Try to solve what you can solve by yourself, and ask for help if you really can't solve it

Anonymous users2024-02-11Minus 5 to the power of 10 = 1/5 to the power of 10
Because minus 5 power of 10 = (0-5) power of 10 = 0 power of 10 5th power 10 = 5th power of 10.

Anonymous users2024-02-10Minus 5 times of 10 = minus 1 of 10 to the power of 5.
Minus 1 to the power of 10 = 1 10
1 10 to the 5th power = 1 100000

Equal to 1 10 to the fifth power.

Anonymous users2024-02-08It's called scientific notation, and for the sake of your understanding, I'll put it this way:
is equivalent to moving the decimal point to the left by a few places, so the minus fifth power is equal to.
You get the idea.
Solution: a=3 to the 55th power = (3 to the fifth power) to the 11th power. >>>More
The -1 power of 3 is one-third.
The process is as follows: >>>More
The 44th power is the 22nd power, which is the 11th power, equal to the 10th power multiplied. It is multiplied by the power of 5, equal to the power of 4 times to the power of 2, i.e. to the power of 6. That is, to the 3rd power, equal to the 2nd power multiplied. >>>More
1. If the 2nd power of (a b) = 5 and ab = 1, then a-b = (1). >>>More
8 to the 2008 power is equal to 2 to the 2008 * 3 power, 2 to the first power is 2, 2 to the power is 4, the third power is 8, the 4th power is 16, the 5th power is 32, look, the mantissa is 2 again, I will analyze it, the 6 at the end, remember.
