Answer 2

Hello dear!!!

Good morning :-)

Here is your answer,

${( - 5)}^{4} \times {( - 5)}^{6} \div {( - 5)}^{9} \\ \\ as : \: {a}^{n} \times {a}^{m} = {(a)}^{n +m } \\ \\ = {( - 5)}^{4 + 6} \div {(5)}^{9} \\ \\ = {( - 5)}^{10} \div {( - 5)}^{9} \\ \\ as : {a}^{n} \div {a}^{m} = {(a)}^{n - m} \\ \\ = {( - 5)}^{10 - 9} \\ \\ = {( - 5)}^{1} \\ \\ = - 5$


Hope it helps.
