Think of ...as: idioms
The inverse of a number or fraction is the reciprocal. 5/8 is 8/5
When you see this just turn the base into a fraction by putting a 1 over it and proceed as you would with a nonnegative exponent so 3^-2=(1/3)^2=1/9

Make sure that the bases are the same. To multiply - add the exponents and multiply the coefficients - and to divide - subtract the exponents and divide the coefficients - 3x^25x^3=15x^5 and 15x^6/3x^2=5x^4
When multiplying two or more fractions - just multiply their numerators and then their denominators. Dividing fractions works a lot like multiplying fractions - with one important extra step. To divide fractions - multiply the first by the reciprocal
