To answer this, first try to answer thexfollowing: what is x in this equation? 9 = 3
what is x in this equation? 8 = 2x
• Basically, logarithmic transformations ask, “a number, to what power equals another number?”
• In particular, logs do that for specific numbers under the exponent. This number is called the base.
• In your classes you will really only encounter logs for two bases, 10 and e.
Log base 10
We write “log base ten” as “log10” or just “log” for short and we define it like this:
If y=10x So, what is log (10x) ?
then log(y)=x
log (10x) = x 10log(x) = x
How about 10log(x)
More examples: log 100 =
log (105)=
?
2 5
• The point starts to emerge that logs are really shorthand for exponents.
• Logs were invented to turn multiplication problems into addition problems.
Lets see why.
log (102) + log (103) = 5, or log (105)

Answer:
image isn't loading for me :((( can you try replying to me w the question
<span>yes it is a true equation.. you can solve it to find q ...
-5(3-9) 4 = 5q - 11
</span><span>−5 *−6 * 4= 5q−11</span><span>120 = 5q−11
120 + 11 = 5q
131 = 5q
q = 131/5
in decimals q = </span><span> 26.2 ..

Hope it helps!!!!
