Does anyone know how to do the "P.I.A.N.3"? Performing four of the arithmetic operations using like and unlike radical terms and expressing the result in the simplest form? Please help :'l

Answer 1

\[3\sqrt{5}+5\sqrt{5}-3\sqrt{5}\]

Answer 2

Answer choices are..
11 radical 5, 5 radical 5, radical 25, & 25

Answer 3

Treat the \[\sqrt{5}\] as you would an x or x^2 ... in a polynomial

Answer 4

So.. would the answer be 5 radical 5?

Answer 5

yes

Answer 6

Thanks I think I get it now.

Answer 7

Great : )

Answer 8

Wait how about if it's \[-8\sqrt{7}-\sqrt{36}-5\sqrt{63}\]

Answer 9

Would it be \[-3\sqrt{92}?\]

Answer 10

-8√7 - 6 -15√7

Answer 11

-8√7 - 6 -15√7
√7 (-8-15) -6
i got -23√7 -6

Answer 12

I don't get it :l

Answer 13

√63 simplifies to 3√7

Answer 14

Okay thanks, how about this one. \[\frac{ 4\sqrt{3}-\sqrt{3} }{ 6 }\]

Answer 15

Would it be 24?

Answer 16

√3( 4-1) / 6
sorry
it's √3/2

Answer 17

My answer choices are radical 3 over 2, 2 over 3, 2, 6, and 0. So the answer would be the first choice right?

Answer 18

yep

Answer 19

How about Darin simplified \[5\sqrt{5}+2\sqrt{5}\] and got 15.7
Martha simplified the same expression and got 50.Use a calculator to determine who got the correct answer?
