Please solve the following questions with fill solution. Thanks.?

1.
(ln(e³))²
=(3ln(e))²
=3²
=9
Answer (D)

2.
(log4_2 + log4_8) / log2_4
= log4_16 / log2_4
= 2/2
= 1
Answer (B)

3.
y = log3_x
= logx/log3
= lnx/ln3
dy/dx = 1/(xln3)
dy/dx|(x=3)=1/(3ln3)
Answer (A)

{ln(e^3)}^2
=3^2
=9
D

2
(log4_2+log4_8)/log2_4
=1
(B)

3
y=(log x)/(log 3)
dy/dx=1/(x In 10)(log 3)
dy/dx|(x=3)=1/(3 In 10)(log 3)
(A)

1
{ln(e^3)}^2
=(3lne)^2
=3^2
=9
2

(log4_2+log4_8)/log2_4
=log4_16/log2_4
=2/2
=1
(B)
3
y=log3_x=logx/log3=lnx/ln3
dy/dx=1/(xln3)
dy/dx|(x=3)=1/(3ln3)
(A)
