-3 to the power 4 into 3 to the power -4 result in 1 as they cancel each other. This means that they are equal but prima facie they don't seem to be equal. Please explain the mystery behind this.

(-3)4 x (3)-4 
= (3)4 / (3)
= 1 
This gives (-3)4 = 1/(3)-4 
Hence, they both are not equal. One is the reciprocal of the other.
