Is the goal to simplify? You just need to multiply the exponents for each factor:

(2z^2)^(-3)
= 2^(-3) x z^(2 x -3)
= (1/2)^3 x z^(-6)
= (1/8) x (1/z)^6
= 1/(8z^6)

Answer:

(2z^2)^(-3)

= 2^(-3) x z^(2 x -3)

= (1/2)^3 x z^(-6)

The cooper's weight as an adult dog will be 90 pounds.

<h3>What is percentage?</h3>

Percentage, which is a relative figure used to denote hundredths of any quantity. One percent (symbolized as 1%) is equal to 100 parts; hence, 100 percent denotes the complete amount, and 200 percent designates double the amount specified.

A typical method for calculating a percentage is the formula shown below:

  • Determine the total amount of what you want to find a percentage.
  • Divide the number to determine the percentage.
  • Multiply the value by 100.

Calculation for the weight of Cooper as an adult;

Cooper's present weight is 20 pounds.

He will weigh about 350% as much as his current weight.

Calculate 350% of 20 pounds.

= (350×20)/100

= 70

The increment of the weight of Cooper will be 70 pounds.

Thus, the total weight is 20 + 70 = 90.

Therefore, the weight of Cooper after 350% as an adult would be 90 pounds.

The sum of a number and its additive inverse is equal to ?
Zigmanuir [339]

Answer:

Zero

Step-by-step explanation:

To find the additive inverse, you merely change the sign of the number

For Example 5 {5 is the number} + (-5) {-5 is the additive inverse} = 0.

i.e. 6 + (-6) = 0

i.e (-7) + 7 = 0
