ALGEBRA - LESSON 32

Read the paragraph on exponents: make notes in your notebook - which algebraic expression contains an exponent?

Read the paragraph. Make notes in your notebook - by doubling 2^4, what is 2 to the power of 5?

Simplify the expression. The variable represents a nonzero real number (Remember - something to a negative power you put 1 over and the negative power becomes a positive).

Mathematical Equivalence

ON

Simplify. Variables are nonzero real numbers (remember, the expression is simplified when there are no negative powers).

Evaluate the expression for a = -2, and b = -3. Variables are nonzero real numbers.

Mathematical Equivalence

ON

Evaluate the expression for a = -2, and b = -3. Variables are nonzero real numbers (note: the b at the end is to the power of 1. since we are multiplying, we need to add our exponents first!).

Make notes in your notebook - When you are multiplying a positive exponent with a negative exponent, you subtract. When you are dividing two exponents, you...

• add

• subtract

• divide

• multiply

• can't simplify anymore
