Properties of Exponents

The table below lists several properties of exponents. Here, m and n are real numbers.

Name Property Example
Multiplication Property xm · xm = x m + n 54 · 52 = x 4 + 2 = 56
Division Property
Power of a Power Property
Power of a Product Property (xy)n = xn yn (2x)3 = 23 x3 = 8x3
Power of a Quotient Property
Zero Power Property x0 = 1, x ≠ 0 170 = 1
Negative Exponent
 

Example 1

Simplify: 2xy4(3x5y)(x3y5)2

We can drop parentheses around the quantity (3x5y) since it has an exponent of 1. Solution 2xy4(3x5y)(x3y5)2
That is, (3x5y) = (3x5y)1 = 3x5y. Use the Power of a Product Property. = 2xy4(3x5y)(x3·2y5·2)
  Simplify. = 2xy4(3x5y)(x6y10)

= 2xy4 · 3x5y · x6y10
Recall: x = x1 and  y = y1 Multiply the constants, 2 and 3. = 6xy4 · x5y · x6y10
  Use the Multiplication Property of Exponents. = 6x1+5+6 y4+1+10
So, 6xy4 = 6x1y4 and x5y = x5y1. Simplify. = 6x12 y15
  So, the result is 6x12y15.
