Question

i need the answer of find the log of (0.00001427)1/7​

Answer 1

Let x = (0.03457)^(1/7)

Taking log of both sides:

log x = (1/7) log (0.03457)

Characteristic is bar 2 & mantesa, using log table is .5387.

Mantesa is always positive.

Bar 2.5387 = bar 7 + 5.5387.

Making 1/7 th of it (for 7th root),

log x= bar 1 + 0.7912.
