Exercise 27 Page 342

Use the Quotient of Powers Property.

5b

Practice makes perfect

To simplify the given exponential expression, we will use one of the Properties of Exponents, the Quotient of Powers Property.

Quotient of Powers Property
To divide powers with the same base, subtract their exponents.

Let's simplify the given expression using this property.

5b^(- 2)/b^(- 3)

MovePartNumLeft

a* b/c=a*b/c

5* b^(- 2)/b^(- 3)

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

5b^(- 2 - (- 3))

a-(- b)=a+b

5b^1

a^1=a
