Today

• Today we will learn how to simplify rational expressions to make them easier.

Properties• add exponents• multiply exponents• distribute exponent• change the spot and make power

opposite• subtract exponents• distribute exponent

Directions

• Combine Like radicals• Find a property that looks like the problem

and do what the property does.

• Yesterday we learned how to simplify rational expressions to make them easier.

• Today we are doing the same thing but with variables.

Properties• add exponents• multiply exponents• distribute exponent• change the spot and make power

opposite• subtract exponents• distribute exponent

Directions

• Combine Like radicals• Find a property that looks like the problem

and do what the property does.
