Evaluate When...

100

Evaluate when x=2 and y=-3

x² - 4y³

2² - 4(-3)³ =   112

200

Evaluate when x=3, y=-1, and z=-7

2^x + 3(z+y)

2³ + 3(-7+(-1)) =  -16

300

Evaluate when  a=2, b=3, c=-6, d=0

-5a² + 3^b -(a+c) + 4^d

-5(2)² + 3³ -(2+(-6)) + 4⁰  =  12

400

Evaluate when  e=4, f=10, g=2

-(e^g) + f - 2g^e

-(4²) + 10 - 2(2⁴)  =  -38

500
