Now use the exponent rule.

i mean from definition.... is it the only way to find integral?

It's , recognize it in the integral
i do it by riemann integrable.
define LRS and URS, i suceed to show LRS=URS, but cant show that LRS=2sqrt(a)
m...so we can say, becoz derivative of sqrt(x) is that, so the definite integral =2sqrt(x)
You cannot use the Riemann integral over here. The function is even defined on . If you had then it is possible to do it by definition, but not the way you posted the problem.
