Answer» option A suppose a = 1/10 let b = log10[a] => log10[1/10] = b=> 1/10 = 10^b so, the value of b must be -1 hence the value of log10[b] is -ve

Answer»

option A

suppose a = 1/10

let b = log10[a]

=> log10[1/10] = b=> 1/10 = 10^b

so, the value of b must be -1 hence the value of log10[b] is -ve
