what is log square root of m^3/n
----
= (1/2)log[m^3/n]
= (1/2)[log(m^3)-log(n)]
= (1/2)[3log(m)-log(n)]
= (3/2)log(m)-(1/2)log(n)
===========================
A.)1/2 log m-log n
B.)3/2 log m-log n
C.)3 log m-log n/2
D.)log m-log n/2
=================================

Next question is:
What is the characteristic of the logarithm 0.0045
Log(0.0045) = -2.3468
Add 10 and you get 7.6532
So log(0.0045) = 7.6532-10
------------------------------
A.)4
B.)6-10
C.)7-10
D.)8-10
========================================
Last question:
What is the logarithm of 0.0009358
log(0.0009358)
Add 10 and you get 6.9712
So log(0.0009358) = 6.9712-10
===================================
A.)6.97118-10
B.)7.97118-10
C.)8.97118-10
D.)9.97118-10
===============================
Note: This is the way logs were taught 60
years ago when we had to use log tables to
look up each logarithm value. Calculators
changed all that. Thank the lord.
