Can someone show me how to multiply two radicals???

Question

fourthroot(x^3) * fourthroot(x)

I dont know how i would do this...can someone help me please!!??

Answer 1

x^(3/4)*x^(1/4)=x

Answer 2

Simply treat the radical as you would a variable, and multiply the x's. That would be fourthroot (x^4) or x.

It's been a while so I would recommend looking it up.

Answer 3

√a*√b=√(a*b)

√a*√a=√(a*a)=√(a^2)=a

or

fourthroot(x)=x^(1/4)

fourthroot(x^3)=x^(3/4)

fourthroot(x^3) * fourthroot(x)=

fourthroot(x^4)=x

or

x^(3/4)*x^(1/4)=

x^(3/4+1/4)=x^1=x
