17x = 136
x = 8
ANSWER
X = -9
EXPLANATION: you subtract 180 - 70 giving you 110
Equation set up: x + 49 + x + 79 = 110
I'M not sure sorry i just keep getting
1/4x
Is the goal to simplify? You just need to multiply the exponents for each factor:
(2z^2)^(-3)
= 2^(-3) x z^(2 x -3)
= (1/2)^3 x z^(-6)
= (1/8) x (1/z)^6
= 1/(8z^6)
