Question

calcule 3 v8+5v2+4v32

Answer 1

$3\sqrt{8} + 5\sqrt{2} + 4\sqrt{32} = 3\sqrt{4} \sqrt{2}  + 5\sqrt{2}  + 4\sqrt{16} \sqrt{2}  =     3 . 2 \sqrt{2} +5\sqrt{2} +4.4\sqrt{2} =6\sqrt{2} +5\sqrt{2} +16\sqrt{2} =27\sqrt{2}$

Answer 2

V8 = V(2.2.2) = V[2.(2^2)] = 2V2
V2 = V2
V32 = V(2.2.2.2.2) = V[2(2^2).(2^2) = 4V2

3V8 + 5V2 + 4V32 =
3.2V2 + 5V2 + 4.4V2
6V2 + 5V2 + 16V2
27V2
