You move the decimal point forward until it reaches the one so it looks like this:
1.4 x 10⁵ 
the exponent, 5, just tells you how many spaces the decimal point moved.
        
             
        
        
        
Answer:
x=-2 and x=0
Step-by-step explanation:
5(x-2)^2 =  20; divide by 5 both sides
(x-2)^2 = 4; take the square root of both sides
(x-2) = ±2, now set it equal to positive 2 and negative 2
x-2 = 2
x=4
AND
x-2 = -2
x=0
