Answer 2

24r^2*s*t

Explanation:

We can simply the following expression by looking at the which terms are common:

`6*r*s*4*r*t`

We have two of r and according to the product rule we can add there exponents:

`r*r=r^(1+1)=r^2`

Therefore the expression can be simplified as:

`=6*4*s*t*r^2=24*s*t*r^2`
