Question

log value of 0.00001​

Answer 1

Answer:

Here, logx means logarithm of x to the base 10 .

log(0.00001)= log(1/100000)

= log(1) -log(100000)

= log{(10)^0 } -log{(10)^5} [logx -logy =log(x/y)]

= 0 .log10 -5.log10. [log(x^y)=y.logx]

= 0.1 -5.1 [logarithm of x to the base is 1.]

= -5

OR,

log(0.00001)

= log{(10)^-5}

= -5log10

= -5 (ans)
