Question

Simplify:

7 SQRT 3 + 8 SQRT 3 – 2 SQRT 2

A) 13 SQRT 5
B) 13 SQRT 6
C) 15 SQRT 3 – 2 SQRT 2

I was confused if it would be B or C

Answer 1

C

Answer 2

C

Answer 3

okay. so it looks like:\[7\sqrt{3} + 8\sqrt{3} - 2\sqrt{2}\]

The first thing to do is combine like terms. Both \[7\sqrt{3}\] and \[8\sqrt{?}\] have the same radicand in common, so you can combine them to be \[15\sqrt{3}\]

You have the \[-2\sqrt{?}\] left. You can't do anything to that. So, like the two above me have said, your answer will be C: \[15\sqrt{3} - 2\sqrt{2}\]

Answer 4

* i meant both 7(sqrt) 3 and 8(sqrt) 3
