Answer 1

Verified answer

No. 1

[tex]\begin{aligned} \sf \frac{5}{8} \times 9 &= \sf \frac{5}{8} \times \frac{9}{1} \\ \sf &= \sf \frac{5 \times 9}{8 \times 1} \\ \sf &= \sf \frac{45}{8} \\ \sf &= \sf 5 \frac{5}{8} \end{aligned}[/tex]

No. 2

[tex]\begin{aligned} \sf {8}^{2} \div {4}^{3} &= \sf { {(2}^{3} )}^{2} \div {( {2}^{2} )}^{3} \\ \sf &= \sf {2}^{3 \times 2} \div {2}^{2 \times 3} \\ \sf &= \sf {2}^{6} \div {2}^{6} \\ \sf &= \sf {2}^{6 - 6} \\ \sf &= \sf {2}^{0} \\ \sf &= \sf 1 \end{aligned}[/tex]
