Question

Simplify by factoring. Assume that all expressions under radicals represent nonnegative numbers.
3 sqrt 243 x^8

Answer 1

\[\sqrt[3]{243x^8}\]Like that?

Answer 2

27x^4 sqrt 3

Answer 3

3 * sqrt ( 243 * x^8) = 3 * sqrt ( 9 * 9 * 3 * x^4 * x^4) = 3 * 9 * x^4 * sqrt (3)

Answer 4

thus 27x^4 sqrt 3

Answer 5

Thank you all!
