Question

1) Simplify:
$\sqrt{ - 16} + 3 \sqrt{ - 25 } + \sqrt{ - 36} - \sqrt{ - 625}$
​

Answer 1

$\sqrt{16} + 3 \sqrt{ - 25} + \sqrt{ - 36} - \sqrt{625}$

$4 + 3 \sqrt{25} + \sqrt{ - 36 } - \sqrt{625}$

$4 + 3 \sqrt{25} + \sqrt{ - 36} - \sqrt{625}$

$4 + 3 \times 5 + \sqrt{ - 36} \sqrt{625}$

$4 + 3 \times 5 + 6 - \sqrt{625}$

$4 + 3 \times 5 + 6 - 25$

$- 25 + (14 + 15 + 6)$

$- 25 + 25$
