Question

Use rational exponents to write, cbrt(x)*^5√(9x) as a single radical expression.

Answer 1

convert the index to exponentials

Answer 2

3rt = ^1/3

4rt = ^1/4

nrt = ^1/n

Answer 3

that way youve got it in exponentials of xs that are easier to see and work with

Answer 4

\[\sqrt[3]{x}*\sqrt[5]{9x}\]
\[ x^{1/3} *9^{1/5}x^{1/5}\]
\[ 9^{1/5}x^{1/5+1/3}\]
etc ...
