Answer 1

simplify the questions?
1. 4^5 over 4^2

2. 120m^16 over 45m^8

3. 8b^3 over 20b^3

4. 3c^8 over 12c^12

5. x^7 x y^3 x x^8 x y^2

6. -7x^3 x 8x^2

Answer 2

\[\frac{4^5 }{ 4^2} = 4^{5-2} = 4^{3}\]

Answer 3

\[\frac{120m^{16}}{45m^8}=\frac{120}{45}m^{16-8}=\frac{15 \times 8}{15 \times 3}m^{16-8}\]
\[=\frac{8}{3}m^{8}\]
