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:
solve x=(y^2).(x^3)

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:
substitute y with 3 and z with 2

STEP 2:    Now, we need to simplify the terms 32 and 23. For any natural number n, bn means:
b with n factors

So, here it means that 3 is to be multiplied 2 times and 2 is to be multiplied three times.
expand the powers

STEP 3:    The only operation to be performed now is multiplication. We multiply 9 by 8 to get the value of x.
9 multiply 8 gives 72

The value of x is 72.
