Question

PLEASE HELP ASAP!! CORRECT ANSWER ONLY PLEASE!! Simplify. √2(√6 − √10)

Answer 1

2√3 - 2√5

Using the law of radicals

√a × √b = √ab

√2(√6 - √10)

= √12 - √20

= √(4 × 3) - √(4 × 5)

= (√4 ×√3) - (√4 × √5)

= 2√3 - 2√5

Answer 2

  √2(√6 - √10)

= √12 - √20

= $\sqrt{2*2*3}$ - $\sqrt{2*2*5}$

= $2\sqrt{3}$ - $2\sqrt{5}$
