Question

Simplify (20^3)^9: 400^12 400^27 20^27 20^12

Answer 1

the answer would be 20^27

Explanation:

when raising an exponent to an exponent (with parenthesis), simply multiply the exponents;

or to prove it, use expanded form:

(20*20*20)*(20*20*20)*(20*20*20)*(20*20*20)*(20*20*20)*(20*20*20)*(20*20*20)*(20*20*20)*(20*20*20) = 20^27

*you are multiplying 20 by itself 27 times
