Answer 1

a )

$- 2(5 + (3 + 4) ^{2} + \sqrt{ - 125)}$

$- 2(5 + 7 ^{2} - 5)$

$- 2 \times 49$

$- 98$

Total = -98

b )

$\sqrt{49 + } ( {5}^{3} - 100 + (5 + 4) + 6)$

$7 + ( {5}^{3} - 100 + (5 + 4) + 6$

$7 + ( {5}^{3} - 100 + 9 + 6)$

$7 + ( {5}^{3} - 85$

$7 + {5}^{3} - 85$

$7 + 125 - 85$

$7 + 40$

$47$

Total = 47
