Evaluate following.
(a) 6253/4
Solution
(a) 6253/4
Again, let's employ both forms to calculate this one.
6253/4 =( 6251/4 )3 =(5)3 = 125 6251/4 = 5 because 54 = 625
6253/4 = (6253 )1/4 = ( 244140625)1/4 = 125 because 1254 = 244140625
As this part has illustrated the second form can be quite hard to employ in computations. The root in this case was not an apparent root and not specifically easy to get if you didn't know it right off the top of your head.
