Simplify (2a^-3b^2)^3

6b^6/ a9
8b^6/ a^9
6b^5
8b

I'm going to assume that you accidentally missed a set of parentheses and that the expression is
Raise 2, , and to the third power:

When a variable raised to a power is raised to another power, the exponents are multiplied:

Negative powers are the positive power in the denominator:

Therefore, the answer is the second option.

This polygon has 4 sides
180(4-2) = 180(2) = 360 degree
80+90+2x + 3x = 360
170+5x = 360
5x = 190
x= 38
measure of angle t is 2(38)= 76
the answer is c. trust me
hope this !
