Question

how to find the value of the log 0.130

Answer 1

How to find value of log(0.130)/(0.0001)^2
log[0.13/(0.0001)^2]
log[0.13/(10^-4)^2]


log[0.13/10^-8]
log[0.13*10^8]
log(0.13)+log(10^8)
log(0.13)+8≈7.1139
log(0.130)/(0.0001)^2≈7.1139

Answer 2

Explanation:

log $\dfrac{0.130}{(0.0001)^2}$

log $\dfrac{0.130}{(10-^4)^2}$

log $\dfrac{0.130}{10-^8}$

log $\dfrac{130}{1000}$ × 10$⁸$

log130 - log1000 + log10$⁸$

[log10=1, log100=2 & so]

$\sf{2.11 - 3 + 8 log10}$

$\sf{-0.89 + 8}$

≈ 7.11
