Solving an equation: x=(y^2).(z^3)

Question

Solve for x for the equation x=(y^2).(z^3) when y=3 and z=2.

Answer

STEP 1:    Given the equation:
All we have to do here is to substitute the values for y and z in the given equation, and then evaluate x.

We substitute 3 for y and 2 for z in the given equation:
STEP 2:    Now, we need to simplify the terms 3² and 2³. For any natural number n, bⁿ means:
So, here it means that 3 is to be multiplied 2 times and 2 is to be multiplied three times.
STEP 3:    The only operation to be performed now is multiplication. We multiply 9 by 8 to get the value of x.
The value of x is 72.
