I am doing a math test and need help with this problem Simplify the radical expression 3√(5) + 6√(45)
I need the problem worked out, I am doing test 6.8.1

21√(5(

Step-by-step explanation:

6√(9*5)

6*3√(5)

18√(5) + 3√(5) = 21√(5(

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)
