Simplify the expression. Write your answer as a power. <br><br> (-3)^4/(-3)^1​
ELEN [110]

Step-by-step explanation:

Simplify the following:

(((-3)/4)^5)^2

Multiply exponents. (((-3)/4)^5)^2 = ((-3)/4)^(5×2):

((-3)/4)^(5×2)

5×2 = 10:

((-3)/4)^10

((-3)/4)^10 = (-3)^10/4^10:

(-3)^10/4^10

(-3)^10 = (-1)^10×3^10 = 1×3^10:

3^10/4^10

4^10 = (4^5)^2 = (4×4^4)^2 = (4 (4^2)^2)^2:

3^10/(4 (4^2)^2)^2

4^2 = 16:

3^10/(4×16^2)^2

3^10/(4×256)^2

4×256 = 1024:

3^10/1024^2

3^10/1048576

Answer=3^10 / 2^20
