Question

Simplify the radical expression.

sqrt(14q)*2sqrt(4q)

Answer 1

\[\sqrt{14q}*2\sqrt{4q}\]

Answer 2

whats the \[\sqrt{4}\]?

Answer 3

what do you mean? this?\[\sqrt{2*2}\]

Answer 4

yep. since \[\sqrt{4} = 2\] we pull out the two and now we have \[2*2 \sqrt{14q} *\sqrt{q}\] so now we want to multiply \[\sqrt{14q} * \sqrt{q} = \sqrt{14q^2}\] take half of the q power and more it out of the sqrt and now we \[q(2*2) \sqrt{14} = 4q \sqrt{14}\]

Answer 5

omg, I got that and it looked wrong...I did not quite do it that way but I got the same answer...I took up way more paper, lol

Answer 6

lol :) well as long as we got the same answer there is higher percentage that we are right!
