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:
m - 7
Step-by-step explanation:
<u>Step 1: Convert words into an expression</u>
What is the expression for seven is less than m
<em>m - 7</em>
Answer: m - 7
The question asks for the square root of 3*3*5*5
√3*3*5*5
lets multiply the numbers together first
√9*25
√225
now use your calculator and solve for the square root
√225=15
Answer=15
Answer:
Step-by-step explanation:
25%=25/100= 1+4=5
1 is loss on selling price 4 so cost price =1+4=5
Then loss on cost price = 1/5x100=20%

What is a Quadrilateral ?</h3>
A quadrilateral is a polygon with four sides , four angles and four vertices.
It is given in the question that
Quadrilateral BGTS has vertices B (-3, 4), G (-1, 3), T (-1, 1), and S (-4, 2).
A graph has to be drawn of
its image after a translation along (5,0) and a reflection in the x-axis.
The coordinates after translation and reflection is is B (8, -4), G (6, -3), T (6, -1), and S (7, -2).
The image is attached with the answer .
