Answer:
7 a⁴ b³
Step-by-step explanation:
-7 ( -a²)²( - b ³)
- A negative base raised to an even power equals a positive
= -7 ( a²)² ( - b³)
- Multiplying an even number of negative terms make the product positive
= - 7 ( a²)² × b³
- simplify the expression by multiplying exponent
= (-7)( a²*² )× b³
= 7 a⁴ b³
Answer:
Solution given:
(-a²)=-a*-a=a²
-b³=-b*-b*-b=-b³
now
-7(-a²)²(-b³)=-7*a⁴*-b³=-7*-1 *a⁴b³=7a⁴b³
the product is 7a⁴b³.
