Question

Solve this following question ​

Answer 1

Step-by-step explanation:

a)

$\frac{ {a}^{6} }{ {a}^{4} } \times {a}^{5} \times {a}^{0} \\ = {a}^{6} \times {a}^{ - 4} \times {a}^{5} \times 1 \\ = {a}^{6 - 4 + 5} \times 1 \\ = {a}^{7}$

b)

$\frac{ {5}^{15} }{ {5}^{10} } \times {5}^{5} \\ = {5}^{15} \times {5}^{ - 10} \times {5}^{5} \\ = {5}^{15 - 10 + 5} \\ = {5}^{10}$
