First we use product rule
y=x^2lnx
dy/dx = x^2 d/dx (lnx) + lnx d/dx (x^2)
dy/dx = x^2 (1/x) + lnx (2x)
dy/dx = x + 2xlnx
now taking second derivative:
d2y/dx2 = 1 + 2[x (1/x) + lnx (1)]
d2y/dx2 = 1 + 2[1+lnx]
1+2+2lnx
3+2lnx is the answer
To get the answer, divide 36 by 7. And the answer of that is 5.1428571428571429
Answer:
b times l times w........
Answer:
option B and C
Step-by-step explanation:
option B and C
98 divided by 7
1. 98-round to 100
7-round to 10
100 divided by 10=10
So 98 divided by 7 is about 10
That is one way
