def int

is it gint??

hehehe no da its just a brackett

ok....

16
i have reduced it till here ∫ t²dt/(t+1) where t=x^1/4
1

now continue....

tx da

got the ans????

u cn write this as ∫₁¹⁶ dx/√x(1+√x)
now take 1+√x=t
1/2√x=dt =>1/√x=2dt
at x=1,t=2 and at x=16,t=5
putting in the given eq.....we hv
2∫₂⁵dt/t
=>2(log5-log2)
=>2log(5/2)
