Question 1061507: someone please help, I'm at the end of my portfolio that needs to be submitted by 2pm tomorrow... and I need to answer these logarithm questions... I don't know much about this subject so any help would be so appreciated
Assigning values for b and x show that the following properties of logarithm hold true
log_b⁡b = 1
〖log〗_b⁡1 = 0
log_b⁡〖b^x 〗 =x
b^log_b⁡x = x

Assigning values for b, M, N and k, show that the following properties of logarithm hold true
log_b⁡〖(MN)〗 = log_b⁡M + log_b⁡N
〖log_b (〗⁡〖M/N〗) = log_b⁡M - log_b⁡N
log_b⁡〖M^k 〗 = klog_b⁡M
Re-write log_3⁡x + 4log_3⁡〖y 〗 as a single logarithm

You can put this solution on YOUR website!
Here is the definition of a logarithm
:
y = log_b (x), then
:
x = b^y
:
For example
:
Let b = 10
:
1 = log_10 (10), then
:
10 = 10^1
:
That should get you going
