4^(3)√(3x)+ 5^(3) √(10x)

Im getting 64√3x+125√10x

Answer 1

but thats not an answer choice

Answer 2

Answer 3

4^3√3x + 5^3√10x
= x(4^3√3 + 5^3√10)

Answer 4

Could you use the equation button to create the equation for us please? :)

Answer 5

what are your answer choices ?

Answer 6

who?

Answer 7

jane, you factored out \(\sqrt x\), right ?

Answer 8

\[4^{3}\sqrt{3x}+5^{3}\sqrt{10x}\]

Answer 9

post the answer choices please :)

Answer 10

FIRSTLY
they are cube roots! \(\Large \sqrt[3]{3x}\)

Secondly, 2 cube roots cannot add up, and get simplified...

Answer 11

so D!

Answer 12

correct! :D

Answer 13

thank you, i was overthinking it lol

Answer 14

no problem,it happens :)
welcome ^_^

Answer 15

Would you help with one more please? @hartnn

Answer 16

sure :)

Answer 17

\[\sqrt[4]{81} x ^{20} y ^{8}\]

Answer 18

What is a simpler form of the radical expression?
@hartnn

Answer 19

that forth root is entire right ?? covering x and y too ?

Answer 20

\((\sqrt[4]{81 x ^{20} y ^{8}}\))

Answer 21

did you try ? whats your answer ?

Answer 22

in all honesty i do not even know how to solve it :/ im just in a rush to finish

Answer 23

i think its either A or D @hartnn

Answer 24

let me give you a hint then
\(\Large \sqrt{a^2} = |a|\)

we require to put an absolute sign only when the exponent is even number

Answer 25

so D?

Answer 26

@hartnn

Answer 27

correct! :)

Answer 28

yessss lol thank you :D

Answer 29

welcome ^_^
