Question

?

Answer 1

do you know this?
\[a \sqrt{b}=\sqrt{a ^{2}*b}\]

Answer 2

this states that if we want to bring a variable inside square square root sign,then it must be squared....
so now u know this,u can apply it in this manner:\[6h ^{2}\sqrt{3h}=\sqrt{3h*(6h ^{2})^{2}}\]
can u simplify this?

Answer 3

see,i have to bring 9h^2 inside sqrt sign,because options have nothing outside it
i don't know how you got to that expression,but the next step after what i told u is to find
\[(6h ^{2})^{2}\]
do u know how to do it?

Answer 4

no,its \[6^{2}h ^{4}=36h ^{4}\]
got this?

Answer 5

so now going ahead,we got \[\sqrt{3h*36h^{4}}\]
\[=\sqrt{(3*36)*(h*h ^{4})}\]
can u solve further?

Answer 6

absolutely correct :) u understood all steps??
