EXPONENTIAL RULES - Example

Rule 1:To multiply identical bases, add the exponents.

Example 5: Simplify

displaymath65

Answer: tex2html_wrap_inline67

Solution: Since all the bases are identical, you can group them. Recall that if you write out tex2html_wrap_inline69 in terms of multiplication, you will have tex2html_wrap_inline71 times itself 40 times. A much easier way to work the problem is to use the properties of exponents with respect to multiplication: Add the exponents:

displaymath73

You can check the answer with your calculator. Find tex2html_wrap_inline69 , tex2html_wrap_inline77 , and tex2html_wrap_inline79 on your calculator. Multiply them and record your answer. Now find tex2html_wrap_inline67 on your calculator. If the answers are the same, you have correctly worked this problem.
