sqrt((16)(20) + (8)(32)) =
For some reason I just can't get this one right. I've read the explanation but I can't figure it out. The answer is 24.
sqrt(4x4)(4x5) + (2x4)(4x4x2) =
OG #32

If you cant get it that way, just multiply the whole thing out.
It gives you sqrt(320 + 256)
which is sqrt(576) = 24.

Vineesh,
Just telling you what I know and think. I am not the expert.

Another way to do it:
√((16)(20) + (8)(32))
√ (16*20 + 8 * 16 *2)
√ 16 (20 + 8*2)
√ 16 * 36
4 * 6 = 24
√((16)(20) + (8)(32))
√ (16*20 + 8 * 16 *2)
√ 16 (20 + 8*2)
√ 16 * 36
4 * 6 = 24

√(16*20 + 8*32)
=√(16*20 + 8*2*16)
=√(16*(20 + 8*2))
=√(16 * 36)
= 4 * 6
= 24.
