Do not forget to simplify the numerator and denominator separately before dividing.

97/31

Practice makes perfect

By substituting a= 8, b= 4, and c= 16 into the expression and simplifying, we can evaluate it. Make sure that you evaluate according to the order of operations, simplifying each of the powers first, then simplifying the numerator and denominator before finally dividing.

2b + 3c^2/4a^2 -2b

SubstituteValues

Substitute values

2( 4) + 3( 16)^2/4( 8)^2 -2( 4)

Calculate power

2( 4) + 3( 256)/4( 64) -2( 4)

Multiply

8 + 768/256 - 8

Add and subtract terms
