Answer: -2x²r⁷
Explanation:
-6x³r⁷ divided by 3x
Normal division for the numbers. -6/3 = -2
For variables with exponents, work with one variable at a time.
You can't divide x into r, y, or anything else. if the variable has no exponent, and it is the same in the numerator and the denominator it "cancels" x/x =1 it disappears. In this case, there are exponents, so only the lesser value cancels.
If the variable has an exponent, subtract the exponent of the variable in the denominator from the exponent in the numerator. x³/x = x²
There is no r in the denominator, so nothing to cancel. that factor stays the same.
= -2x²r⁷
