What is r to the fourth divided by r to the sixth?

Answer 1

r^(4) / r^(6) = r^(4-6) = r^(-2) = 1/r^(2)

Rules for manipulation of indicies.

#1 ; the coefficient MUST be the same . 'r' in this case

#2 ; for multiplication ; ; add the indices

#3 ; for division ; subtract the indices

#4 ' for 'nesting' ; multiply the indices

Careful something of the nature 'r^(2)' X s^(3)' CANNOT be done as the coefficients ''r' & 's' are different. The coefficients MUST be the same

Answer 2

It is 1 over r squared, or r to the negative second power.
