Question

5√80-12√5

Answer 1

\(5\sqrt{16\cdot 5}-12\sqrt{5}=20\sqrt{5}-12\sqrt{5}=8\sqrt{5}\)

Answer 2

how did you get 20√5

Answer 3

\(5\sqrt{16\cdot 5}=5\sqrt{16}\sqrt{5}=5\cdot4\sqrt{5}=20\sqrt{5}\)

Answer 4

ohhh alright thanks tons

Answer 5

-2√24-3√6 what about this

Answer 6

Hint: \(24=4\cdot 6\) . Now, please give it a try! :)

Answer 7

lol i tried and i got -72√2-3√6 but it looked wrong

Answer 8

Hint 2: \(\sqrt{24}=\sqrt{4\cdot 6}=\sqrt{4}\sqrt{6}\)

Answer 9

\[5\surd 80-12\surd 5 \]\[20 \sqrt{5}-12\surd 5 = 8 \sqrt{5} \]

Answer 10

so -11√6?

Answer 11

almost! but \(-2\sqrt{24}=-2\sqrt{4}\sqrt{6}=-2\cdot2\sqrt{6}=-4\sqrt{6}\)

Answer 12

ugh i give up

Answer 13

Then you have \(-4\sqrt{6}-3\sqrt{6}=-7\sqrt{6}\)
