Evaluate each expression for s=4 and t=8
1) (25)^2t
2) 2st^2-5^2
3) 2s^2-t^3/16

1. 2.328×

2. 487

3. 30.52  OR  0 (see explanation↓)

Step-by-step explanation:

1.

(sub for t=8)

=

=

=2.328×

2.

(sub for s=4 and t=8)

=2×4×-

=512-25

=487

3. (the equation is not clear so I will do as well)

FOR

(sub s=4 and t=8)

=2×-

=32-1.476826146

=30.52 (to the nearest 2 decimal place)

FOR

(sub s=4 and t=8)

=2×-

=32-32

=0
