Question

Simplify. 4 times the 4th root of 128

Answer 1

\[4\sqrt[4]{128}\]

Answer 2

like that right, that is ur question?

Answer 3

well 28 = 2^7

\[4 \times \sqrt[4]{2^7} = 4 \times \sqrt[4]{2^4 \times 2^3} = 4 \times \sqrt[4]{2^4} \times \sqrt[4]{2^3}\]

this may help..

Answer 4

just simplify 2^3 to get the final answer.

Answer 5

@campbell_st i cant simpfly that

Answer 6

@some_someone yea thats it

Answer 7

2^3 = 2x2x2

you can simplify that

Answer 8

this question uses the power of a power index law

\[(x^a)^b = x^{a \times b}\]

and for radicals

\[\sqrt[a]{x} = x^{\frac{1}{a}}\]

so this appears to be what you are being asked about.

Answer 9

slight error in the 2nd line... if thats a solution...

Answer 10

you're missing the radical
