We can use the interest formula:
Let i = interest.
Let p = principal
Let r = interest rate
Let t = time.
I = p × r × t. Plug in our numbers 
6.5% = 0.065
I = $4,000 × 0.065 × 3 = $780.
He will pay $780 in interest after 3 years.

It's long to explain, so heres a picture of how solved each. hope this helps!! :) 
 
        
             
        
        
        
If 4=2^2
8=2^3
(2^)2x+10=(2^)6x
(2^)6x-(2^)2x=10
(2^)2x×7=10, where x has no real value
