JEE Main 17 March 2021, Shift 2, Maths Q67

Question 67 of 90 in this shift, Maths question 7 of 30, Section A.

If the curve y=y(x)y=y(x) is the solution of the differential equation 2(x2+x5/4)dy−y(x+x1/4)dx=2x9/4dx2(x^2+x^{5/4})dy-y(x+x^{1/4})dx=2x^{9/4}dx, x>0x>0 which passes through the point (1,1−43log⁡e2)\left(1, 1-\frac{4}{3}\log_e 2\right), then the value of y(16)y(16) is equal to :
