Answer:
<u>1.</u> 2.328×
<u>2.</u> 487
<u>3.</u> 30.52 OR 0 (see explanation↓)
Step-by-step explanation:
<u>1.</u>
(sub for t=8)
=
=
=2.328×
<u>2.</u>
(sub for s=4 and t=8)
=2×4×
-
=512-25
=487
<u>3.</u>
(the equation is not clear so I will do
as well)
<u>FOR</u> 
(sub s=4 and t=8)
=2×
-
=32-1.476826146
=30.52 (to the nearest 2 decimal place)
<u>FOR</u> 
(sub s=4 and t=8)
=2×
-
=32-32
=0
