Multiplying with exponents

Objectives Use exponent notation. Simplify expressions with positive integer exponents. Define a zero exponent. Simplify expressions with negative exponents Write a number in scientific notation

What is an exponent? What does 25 equal? an a is called the base, n is the power or exponent

Using exponent notation x*x*x*x*x = (3x)(3x)(3x)=

The product rule (x2)(x3) = (102)(106)

Zero exponent a0 = 1

Multiplying multiple numbers and variables (2x2y4)(4x2y2)

Multiplying multiple numbers and variables (10x2y4)(-12x2y2)

Another example (-x2y3)(-2x6y12)(-x7y5)
