Question

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

Answer 1

Answer:

A and C.

Step-by-step 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

Answer:

Option A and C

Step-by-step explanation:

As,

$2 \sqrt{75} + 3 \sqrt{50}$

$= 2 \sqrt{25 \times 3} + 3 \sqrt{25 \times 2} (A)$

$= 2 \times 5 \sqrt{3} + 3 \times 5 \sqrt{2}$

$= 10 \sqrt{3} + 15 \sqrt{2} (C)$
