Answer:

7. 4⁴ = 4x4x4x4=256
4³= 4x4x4=64
4²= 4x416

4¹=4
4⁰=1 ( as every number that has power 0 = 1)

8. (-2)⁴

=(−2)*(−2)*(−2)*(−2)

=(-2)⁴

=16

(−2)³

=(−2)*(−2)*(−2)

=(−2)³

=−8

(−2)²

=(−2)*(−2)

=(−2)²

=4

(−2)¹

=−2

(−2)⁰

=1 ( ( as every number that has power 0 = 1)

Solution:

We know the following rules:

  • Rule: If an exponent is negative, it will be in the fraction 1/nˣ.
  • Rule: If an exponent is positive, it will be in whole number form and will multiply itself m times.
  • Rule: if a number's exponent is 0, then the number is 1.

Now, let's solve each problem.

Question-7

  • 4³ = 4 x 4 x 4 = 64
  • 4² = 4 x 4 = 16
  • 4¹ = 4
  • 4⁰ = 1

Question-8

  • (-2)³ = (-2) x (-2) x -(2) = -8
  • (-2)² = (-2) x (-2) = 4
  • (-2)¹ = -2
  • (-2)⁰ = 1

Hoped this helped!
