Exercise 16 Page 366

Use the Quotient of Powers Property.

8 * 10^(11)

We want to evaluate the given quotient. To do so, we will rewrite it as a fraction. Then, we will use the Quotient of Powers Property.

(9.6 * 10^7) ÷ (1.2 * 10^(- 4))

a÷ b=a/b

9.6* 10^7/1.2* 10^(- 4)

Write as a product of fractions

9.6/1.2 * 10^7/10^(- 4)

Calculate quotient

8 * 10^7/10^(- 4)

a^m/a^n= a^(m-n)

8 * 10^(7-(- 4))

a-(- b)=a+b

8 * 10^(11)

Our result is already written in scientific notation.
