Question

really don't get this question, please help!

Answer 1

@campbell_st

Answer 2

but, not sure if its correct

Answer 3

what slope did you get...?

Answer 4

B looks to be correct

Answer 5

I agree that seems to B correct.

Answer 6

@BigPoppa117 @campbell_st

Answer 7

ok... so the question is

\[2\sqrt[4]{80}\]

so you need to rewrite the radical as the product of factors

\[2\sqrt[4]{80}= 2 \sqrt[4]{16 \times 5}\]

which can be written as

\[2 \times \sqrt[4]{16} \times \sqrt[4]{5}\]

now you should be able to work from there

Answer 8

ok, I need a little guidance still on the last step... please

Answer 9

would I do 16 times 5? and then add the exponents

Answer 10

or would I distribute the 16 to 4 times 4 to get 8 on the outside?

Answer 11

@campbell_st ? still need help...

Answer 12

well you need to know

\[16 = 2^4\]

so now you should be able to simplify the problem

Answer 13

@zepdrix

Answer 14

so the problem becomes

\[2\sqrt[4]{80} = 2 \times \sqrt[4]{2^4} \times \sqrt[4]{5}\]

just simplify the 1st radical
