The given expression is

49 is the square of 7 and 64 is the square of 8.

So we can write the given expression as

Rational expressions work like this: if you raise a number x to the power m/n, it means that you're considering the n-th root of x^m.

So, in this case, you are considering the second root (i.e. the square root) of 49/64 to the first power, i.e. 49/64 itself. In formula, you have

Since there is a minus sign in front of the whole expression, the answer is -7/8

yor answer is 7/6 times 5

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)
