Logarithms Question no. 16 The value of looks_one 1 looks_two 4 looks_3 2 looks_4 3 Answer Option looks_one 1 Solution Solution : Question no. 17 If log 4 7 = x, then log 7 16 is equal to looks_one 2/x looks_two x looks_3 x 2 looks_4 2x Answer Option looks_one 2/x Solution Solution : log 4 7 = x 1/log 7 4 = x 1/log 7 (16) 1/2 = x 2/log 7 (16) = x log 7 (16) = 2/x Question no. 18 If n=2017! then is looks_one 0 looks_two 1 looks_3 n/2 looks_4 n answer Option looks_two 1 Solution Solution : Question no. 19 log(ab)-log|b|= looks_one log a looks_two log|a| looks_3 -loga looks_4 none of these Answer Option looks_two log|a| Solution Solution : log(ab)-log|b| = log |ab/ b| = log|a| Question no. 20 If log 4 5=a and log 5 6=b , then log 3 2 is equal to looks_one 1/(2a+1) looks_two 1/(2b+1) looks_3 2ab+1 looks_4 1/(2ab-1) ...
