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.
