Ho do i do this problem ? lolhttp://www.wolframalpha.com/input/?i=7h%5E2+sqrt%283h%29 @hartnn

Answer 2

try this :

http://www.wolframalpha.com/input/?i=7h%5E2+sqrt%283h%29&a=*MC.h%5E2-_*Variable-&a=UnitClash_*h.*Hours.dflt--&a=ListOrTimes_Times

Answer 3

which part would i check ?

Answer 4

yeah, you had to click on
Use h as variable...

Answer 5

bdw, what you got ?

Answer 6

it doesnt show the answer .-.

Answer 7

what you wanto do.. simplify or send everything inside radical ? wats the q...

Answer 8

im supposed to find the equation that simplifies to that

Answer 9

looks, you just need to send outside stuff to inside

Answer 10

by multiplying ?

Answer 11

\(7h^2\sqrt{3h} \)

Answer 12

7 = \(\sqrt{7} \times \sqrt{7}\) = \(\sqrt{49}\)

Answer 13

7 becomes 49, when u take it inside radical

Answer 14

ok and what do i do with the h

Answer 15

it becomes h^3 ?

Answer 16

\(7h^2\sqrt{3h} \)

\(h^2\sqrt{49 \times 3h} \)

Answer 17

nopes,

h^2 = \(\sqrt{h^2} \times \sqrt{h^2} = \sqrt{h^?} \)

Answer 18

h^2?

Answer 19

h^2 = \(\sqrt{h^2} \times \sqrt{h^2} = \sqrt{h^\color{red}{4}}\)

Answer 20

oh i thought it stays the same but ok

Answer 21

if u take h^4 out of radical , it becomes h^2 again.

write the final expression

Answer 22

\(7h^2\sqrt{3h} \)

\(h^2\sqrt{49 \times 3h} \)

\(\sqrt{h^4 \times 49 \times 3h} \)

Answer 23

you can simplify a bit. i think they wanted this when they asked to "find the equation that simplifies to that "

Answer 24

these r my choices :

sqrt(14h^3)
sqrt(49h^3)
sqrt(147h^5)
sqrt(21h^5)

Answer 25

great ! simplify the thing above and see what u get :)

Answer 26

7 sqrt(3) sqrt(h^5)

Answer 27

wait no sqrt(147h^5)

Answer 28

brilliant !

Answer 29

thank you do much! :)

Answer 30

np :)
