Question

[10.06] What is the product of 3the square root of u. (the square root of 448. + 4the square root of 7.)? Simplify if possible.

Answer 1

\[3\sqrt(u)(\sqrt(448)+4\sqrt(7)) = 3\sqrt(u)* (4\sqrt(7)+ 8\sqrt(7))\]
=
\[3\sqrt(u)\sqrt(7)(12) = 36\sqrt(7)\sqrt(u)\]

Answer 2

That looks kind of ugly, but did you follow?

Answer 3

i had options for answers lke this 24the square root of 7 times u. + 4the square root of 7.
204the square root of 7 times u.
24uthe square root of 7.
36the square root of 7 times u.

Answer 4

Is this what the problem looked like?
\[3\sqrt(u)* (\sqrt(448)+ 4\sqrt(7))\]

Answer 5

yep

Answer 6

Ok is the last answer
\[36\sqrt(7u)\]?

Answer 7

That is the answer if it looks like that because
\[\sqrt(7)\sqrt(u) = \sqrt(7u)\]
