PLEASE HELP WILL GIVE MEDAL


What is the exact value of the expression 8 times square root of 15 + 5 + square root of 5 plus squareroot of 15

Answer 1

\[8\sqrt{15}+5+\sqrt{5}+\sqrt{15}\]

Answer 2

is that right?

Answer 3

yes!

Answer 4

okay, well the best way(in my opinion to do this) is to factor out the square roots

Answer 5

you can add them since they have the same \[\sqrt{5}\]but don;t change the \[\sqrt{5}\]just like \[\sqrt{5}+\sqrt{5}=2\sqrt{5}\]

Answer 6

i still don't follow

Answer 7

here: \[8\sqrt{5}+5+\sqrt{5}+\sqrt{5}\rightarrow 5+10\sqrt{5}\]\[8+1+1=10\]this has the same \[\sqrt{5}\]so just add the number

Answer 8

so would it be \[8\sqrt{15} + 5\sqrt{15}\]

Answer 9

@Lynncake
