Question

(x^-3)^-5x^6

can someone help me with this please?

Answer 1

Do you have a choice like this?:
x^21

Answer 2

yeap that was the answer haha thanx

Answer 3

(x^(-3))^(-5)x^(6)

Remove the negative exponent in the numerator by rewriting x^(-3) as (1)/(x^(3)). A negative exponent follows the rule: a^(-n)=(1)/(a^(n)).
x^(6)((1)/(x^(3)))^(-5)

Multiply 3 by 5 to get 15.
(1)/((1)/(x^(15)))*x^(6)

To divide by (1)/(x^(15)), multiply by the reciprocal of the fraction.
x^(15)*x^(6)

Remove all negative exponents in the expression x^(21).
x^(21)

Hope this helps. :)
