Answer 2

Answer:

$( {a}^{4} \times {a}^{3} ) \div {a}^{5} \\ \\ (bases \: are \: same \: so \: we \: add \: the \: exponents \: \\because \: bases \: are \: in \: multiplication) \\ \\ ( {a}^{4 + 3} ) \div {a}^{5} \\ \\ = > {a}^{7} \div {a}^{5} \\ \\ (bases \: are \: same \: so \: we \: subtract \: the \: exponents \\ because \: bases \: are \: in \: division) \\ \\ = > {a}^{7 - 5} \\ \\ {\boxed {\red{answer= > {a}^{2}}}}$
