An example would be  1/3  as an exact answer  and 0.33 as an approximate answer because 1/3 = 0.333.....  - a recurring decimal where there are an infinite number of 3's. 0.33 would be correct to the nearest hundredth.

Radicals are exact answers :- like  √2 , √5 .  Approximate value for √2 is 1.414
Approximate means about, and exact means, spot on, not approximate, like the exact answer of 3+3 is 6 hope it helps!!
