Exercise 54 Page 13

Be sure to evaluate the numerators and the denominators separately, according to the order of operations.

1/2

Practice makes perfect

Let's start by substituting a= 8, b= 4, and c= 16 into the expression. Then we will need to evaluate the numerators and denominators separately, taking care to evaluate powers before multiplying, adding, and subtracting.

2a-b^2/ab + c-a/b^2

SubstituteValues

Substitute values

2( 8)- 4^2/8( 4) + 16- 8/4^2

Calculate power

2( 8)-16/8( 4) + 16-8/16

Multiply

16-16/32 + 16-8/16

Subtract terms

0/32 + 8/16

Calculate quotient

0+8/16

Add terms

8/16

a/b=.a /8./.b /8.
