Question

Help, i've been trying for around 30mins and I can't figure it out.

Answer 1

A and C.

Explanation:

2 √75 + 3√50

= 2√(25*3) + 3√(25*2)

- so A is one.

2 √75 + 3√50

= 2√25√3 + 3√25√2

= 2*5√3 + 3*5√2

= 10√3 + 15√2

which is C.

Answer 2

Option A and C

Explanation:

As,

`2 √(75) + 3 √(50)`

`= 2 √(25 * 3) + 3 √(25 * 2) (A)`

`= 2 * 5 √(3) + 3 * 5 √(2)`

`= 10 √(3) + 15 √(2) (C)`
