Question

(^5sqrt x^7)^3 show step by step how to do it

Answer 1

Perhaps you meant [(√(x^7))^(1/5)]^3

The fifth root of the square root of x to the seventh cubed?

√(x^7)=(x^7)^(1/2)=x^(7/2)

(x^(7/2))^(1/5)=x^(7/10)

(x^(7/10))^3

x^(21/10)

Sorry I did my best to decipher what you wanted to express.

In general:

(a^b)^c=a^(b*c)  just work from the inside to the outside...
