Answer 1

Answer:

solution,

${3}^{2} \times {10}^{5} \times 25 \div {5}^{7} \times {6}^{5} \\ = {3}^{2} \times {5}^{2 \times 5} \times {5}^{2} \div {5}^{7} \times {3}^{2 \times 5} \\ = {5}^{10 + 2 - 7} \div {3}^{10 - 2} \\ = {5}^{5} \div {3}^{8}$

Hope it helps

Answer 2

Given,

$iii. \frac{ {3}^{5} \times {10}^{5} \times 25 }{ {5}^{7} \times {6}^{5} }$

$iv. \frac{ {3}^{8} \times {a}^{6} }{ {9}^{3} \times {a}^{3} }$Solution:

III.

$\frac{ {3}^{5} \times {10}^{5} \times 25 }{ {5}^{7} \times {6}^{5} } = \frac{ {3}^{5} \times {5}^{5} \times {2}^{5} \times {5}^{2} }{{5}^{7} \times {6}^{5} } \\ = \frac{ {3}^{5} \times {5}^{7} \times {2}^{5} }{{5}^{7} \times{2}^{5} \times {3}^{5} } \\ = 1$

IV.

$iv. \frac{ {3}^{8} \times {a}^{6} }{ {9}^{3} \times {a}^{3} } = \frac{ {3}^{8} \times {a}^{6} }{ {3}^{6} \times {a}^{3} } \\ = {3}^{2} \times {a}^{3} \\ = 9 {a}^{3}$
