n 2 n how to dissolve n

Your question is 2 (n-1)=256, right? Then the analysis is as follows: 2 (n-1)=256 because 256=2 8%d%a so n-1=8 I hope it can help you, I wish you progress in learning%d%aFollow-up:

d%a[2+2 (n -1)] n -1) how to simplify %d%a:%d%a directly, you can %d%a [2+2 (n -1)] n -1)=2(n-1)+(n-1)*2 (n-1)=2n-2+(n-1)*2 (n-1)%d%a ask: %d%a The answer is not right%d%a:

d%a[2+2 (n -1)] n -1) Check your question to see if there are any mistakes. Because if it's [2+2 (n -1)] n -1), it's okay, and there's no common factor %d%a to ask: %d%a is not wrong%d%a:

d%a, [2+2 (n -1)] n -1) can only be multiplied, like a(b+c)=ab+ac This is all basic, I believe you will do the math yourself. In addition, the so-called correct answer after hi is not necessarily correct, and may be wrong due to typographical errors and corrections. %d%a

Doesn't that equal -2?

Solution: (n 2) = 360 4 180

Type potato n Sansong 2) Chong rent Zheng = 8

n=8+2n=10

n-2) 180°=360°x4 How can there be no hail in the hall?

n-2=360x4÷180

n-2=8n=8+2

n=10

The answer to this question is:

n is equal to 10, if you agree, please give it a like, thank you.

It is known that 180°*2=360°

The demolition allowed the observation and accompanying the attack, and carried out the chaos of the transfer.

n-2)*180°=360°*4

n-2)*180°=180°*2*4

n-2=8n=10

n+2=n solution: The rubber tan is slow down like a chain item, get.

n+n=2 merge the same kind of disturbance grandchildren, obtained.

2n=2 coefficient to 1. n=1

To solve this equation, you need to move the variables to one side of the equation, move the constants to the other side of the equation, and then simplify. For this equation, the following steps can be used:

n + 2 = n

Move n to the left of the equal sign and 2 to the right of the equal sign

2 = n + n

Merge the items of n:

2 = 2n

Move the coefficient of Xiangyu n to the right:

180°-120° 60° according to the sum of the outer corners of all polygons trouser pie equals 360°

360 60 Hypometic 6 so it is a hexagonal pulse pure ridge.

Laugh high n - take the track 2) know the rise and 180°=nx120°180°n-360°=i20°n

i80°N-i20°N=360°

60°n=360°n=6

n²+5n-104=0(n+13)(n-8)=0

n = -13 (rounded), n = 8

The Law of Division:

The dividend and the divisor are multiplied or divided by the same number (except zero) at the same time, and their quotient does not change. a÷b=(a×c)÷(b×c)=(a÷c)÷(b÷c) (c≠0)

The calculation rules of division, divisor = dividend quotient, dividend = quotient * divisor dividend divisor = quotient.

Dividend quotient = divisor.

Quotient divisor = dividend.

√3/√3=1,√12=2√3

So the original formula: =1+2-2 3

That's it, 3-2 3 is the final answer.

The numerator and denominator of the previous fraction are multiplied by (root 3-2) The numerator is obtained by (3-2 times the root 3) The denominator is obtained by the square difference formula: 1 root, 12 = 2 times the root, 3 times, so the whole formula = 3-2 times the root, 3 + 2 times the root, 3 = 3
