Question

3 root 45 - root 225 + root 400 minus root 50

Answer 1

Let see your answer !!!!!

3√45 - √225 + √400 - √50

$3 \sqrt{9 \times 5} - 15 + 20 - \sqrt{5 \times 10} \\ \\ = 3 \sqrt{3 \times 3 \times 5} + 5 - \sqrt{5 \times 5 \times 2} \\ \\ = 3 \times 3 \sqrt{5} + 5 - 5 \sqrt{2} \\ \\ = 9 \sqrt{5} + 5 - 5 \sqrt{2}$
