Question

√¯32 + 2/√¯2 - √¯2/9
How to simplify?

Answer 1

well you need to recognise

32 = 16 x 2

so then

\[\sqrt{32} = \sqrt{16 \times 2} = \sqrt{16} \times \sqrt{2}\]

so you need to simplify this...

then you have 3 like terms that can be added and subtracted....

hope it helps

Answer 2

Yeah i know this. 4√¯2
But what about others?

Answer 3

As champbell_st said:

\[\sqrt{\frac{ 2 }{ 9 }} = \frac{ \sqrt{2} }{ 3 } = \frac{ 1 }{ 3 }\sqrt{2}\]

4sqrt(2) + 2sqrt(2) - 1/3 sqrt(2)
sqrt(2) [ 4 + 2 - 1/3]
sqrt(2) [ 12/3 + 6/3 - 1/3]
sqrt(2) [ 12 + 6 - 1/3]
sqrt(2) [17/3]

Answer 4
