Evaluate the following algebraic expressions: 1.) 40y-¹, y = 5 2.) 1/m-²(m + 4), m = -8 3.) (p² – 3)-², p = 14.) (x – 1)-² / (x + 1)-², x = 2 5.) y-³ – y-², y = 2

Perform the calculations as follows.

1. 
 = 40*y = 40*5.2
 = 208

2. 
 = m²(m+4)
 = (-8)²*(-8+4)
 = -256

3. (p² - 3)⁻², p=1
 = 1/(p² - 3)²
 = 1/(1 - 3)²
 = 0.25

4. 
 
 = 3.5²/1.5²
 = 5.444

5. y⁻³ - y⁻², y=2
 = 1/y³ - 1/y²
 = 1/8 - 1/4
 = -1/8
