If 100.3010 = 2, then find the value of log0.125 (125) ?

A. 699 / 301

B. – 699 / 301

C. – 1

D. – 2

Answer : B. – 699 / 301...


Explanation:

    100.3010 = 2 ,
    take log base 10 both sides ,
    log10100.3010 = log102
    0.3010 = log102

    Given :
    log0.125125 = log125/1000125
    = log0.55 = 1 / log50.5
    = 1 / -log52
    = -log105 / log102
    = -2.321 [ log5 = 0.6989 and log2 = 0.3010]
