I know that d^-3 goes on the bottom to make it positive;however,does -30 go on the bottom as well? Please explain the rule(s) for this. Thanks
(-5)*(6) = -30
why would you want it to go on the bottom?
(d^-5)(d^2) = d^(-5+2) = d^-3
The negative exponent says it goes on the bottom. The -30 has no exponent; it's just a number. It's just a negative number, not a negative exponent.
To put it on the bottom would be like saying -6 = 1/6 Nope.
So, -30/d^3 is the final answer
