Question

simplify
2√6 * √5 + 4√6 *√5-√6

6√24

12√30

6√11 - √6

6√30 - √6

Answer 1

What do all the terms have in common?

Answer 2

there all factors??

Answer 3

I only see the \[\sqrt{6}\]

Answer 4

in all three

Answer 5

yea i do to so does that mean all 3 of those are wrong

Answer 6

nope... let me look

Answer 7

ok sorry im really bad at this

Answer 8

They don't really simplify... my best ans is \[\sqrt{6}(6\sqrt{5}-1)\]. But they ignore the last term at first and multiply \[\sqrt{5}\sqrt{6}=\sqrt{5*6}\]

Answer 9

so... \[\sqrt{5*6}(2+4)-\sqrt{6}\]

Answer 10

so its D

Answer 11

apply the exponent rules for combining the multiplied roots,
\[\sqrt{a}*\sqrt{b}=\sqrt{a*b}\]
combine terms,
the root(6) is still left

Answer 12

\[2\sqrt{30}+4\sqrt{30}-\sqrt{6}\]

\[6\sqrt{30}-\sqrt{6}\]

Answer 13

you can combine the same roots, not different ones, when they are added together

Answer 14

yea i figured it out thanks you are the one that actually makes me understand this problem

Answer 15

just have to remember like 4 or 5 of them exponent rules , combining things right

Answer 16

becuase, recall a square root is the same as 'to the 1/2' power

Answer 17

will do thanks
