Answer 1

$a) \: \frac{ {(5 \times 5)}^{2} + {( - 3)}^{3} \div {( - 3)}^{2} }{ {10}^{0} }$

$\frac{ {25}^{2} - 3}{1}$

${25}^{2} - 3$

$625 - 3 \\ 622$

$b) \: \frac{ { - 2}^{3} + {(6 \div 6)}^{2} - {0}^{12} }{ { - 2}^{3} }$

$\frac{ - 8 + {1}^{2} - 0}{ - 8}$

$\frac{ - 8 + 1}{8}$

$\frac{ - 7}{ - 8}$

$\frac{7}{8} = 0.875$
