z squared - 7/3z + 10/9

i believe cause it wouldn't convert my repeating decimal into a fraction..

I multiplied z by everything on the other side and then i multiplied -5/3 to the same side as i did z then i combined like terms

<h3>Answer: 8</h3>

Reason:

Replace p with 2 and evaluate.

$p^3 = 2^3 = 2*2*2 = 8$

Think of a cube that is 2 units along each side. It's volume is 2*2*2 = 8 cubic units. Repeated multiplication can be shortened to using exponents.

Another example: $7^4 = 7*7*7*7$
