Answer 1

a) ${y}^{9 + 13 + 8 - 10} = {y}^{20}$

b)$\frac{ {x}^{20} }{ {x}^{15} } = {x}^{5}$

c) $\frac{ {b}^{30} . {b}^{ - 13} }{ {b}^{23} } = \frac{ {b}^{17} }{ {b}^{23} } = {b}^{ - 6}$

d) $\frac{ {m}^{8} . {m}^{ - 7}. {m}^{16} }{ {m}^{4}. {m}^{15} } = \frac{ {m}^{17} }{ {m}^{19} } = {m}^{ - 2}$
