By PEMDAS (or any alternative), <em>the first step should be to divide</em>, as D comes before A. So, 16 ÷ 4.
For the numeric part, you'll have to find the GCD of 15 and 25, which is 5. So, we can factor a 5 and we have

As for the literal part, you can factor
because it's the power of s with the smallest denominator. So, we have
