Question

Which expression shows the first step in dividing 5x 3 by x??

Answer 1

The very first step is to express
`x^(3)` as x*x*x. You can then proceed to cancel on the x with the x in the denominator to be left with 5*x*x in the numerator. This gives a result of
`5x^(2)`

Answer 2

If we want to divide 5 x³ by x we must first use:
x ^m : x^n = x ^ ( m - n )
5 x³ : x = 5 x ^(3 - 1) = 5 x²
