Answer:

1. -10f³g⁸

2. a²⁰

3. 27e¹²

4. 10

5. 7a²

Process:

1. 5*(-2) = -10 [ multiply the constant ]

f² * f = f³ [ add the exponent of variables f]

g*g³* g⁴ = g⁸ [add the exponential of variables g]

= -10f³g⁸

2. a⁴*⁵ =a²⁰ [ multiply the exponent of 4 by 5]

3. 3*3*3 = 27 [multiply the constant by itself 3 times]

e⁴*³ = e ¹² [times the exponent of variables e by 3]

=27e¹²

4. 10⁷ ÷ 10 ⁶= 10(⁷-⁶) [subtract the exponent of denominator from exponent of numerator]

=10¹ or simply, 10

5. 7a⁵ * a⁴ = 7a⁹ [add the exponent]

7a⁹ ÷ a⁷ = 7a² [subtract the exponent of denominator from the exponent of numerator]

That's all, I'm pretty not sure^-^
