Review:

Exponent Laws

  • ^ refers to an exponent.  3^3 refers to 32.
  • use / to represent divide and * to represent multiply.
  • use + and - for add and subtract.
  • any letter can be used as a variable.

product law

xmxn = xm+n

power of a product law

(xy)m = xm  ym

power of a power law

(xm)n =xmn

quotient law

xm/ xn = xm-n

power of a quotient law

(x/y)m = xm ym

1/x-m = xm
