If ln a=2 , ln b=3 , and ln c=5 , evaluate the following:
d. (In c^-4)(In a/b^2)^4''.
(-4In5)(In(2)-In2(3))^4. = -40-(6^4)=-40-1296=1256. 1256 Was the ANSWER I GOT

.
If ln a=2 , ln b=3 , and ln c=5 , evaluate the following:
d. (In c^-4)(In a/b^2)^4''.
----------------------------------------------------------

. = . . * = (-4)*5 * 4* ( ln(a) - 2*ln(b) ) = (-4)*4*(2 -2*3) = . . .

Can you complete these calculations?

Sorry! That answer's incorrect.

ln a = 2; ln b = 3; and ln c = 5
 


 =  -------->  ------> ln 1 – 4 * ln c -------> 0 – 4 * ln c -----> - 4 * ln c
 =  ------> 


 now becomes: 


 ------- Substituting 2 for ln a; 3 for ln b; and 5 for ln c
