Answer:
9
Step-by-step explanation:
a^2 + b^2 = h^2
15^2= 12^2 + b^2
225=144+b^2
81=b^2

We have to represent the fraction
in two different ways.
Let us multiply the numerator and denominator of the given fraction by '2'.
Therefore, 
Therefore,
is the first way to represent the given fraction.
Now, Let us multiply the numerator and denominator of the given fraction by '3'.
Therefore, 
Therefore,
is the second way to represent the given fraction.
Therefore,
and
are the different ways to represent the fraction
.
5^3=125; 2.5^2=6.25. So the answer to your first question is 125, and the second one is 6.25
Answer:

Step-by-step explanation:
Here, the given expression is:

Now, by logarithm rules, we know
if 
, then x =
Comparing here, b = 10 and z = 2
⇒ y = 
or,

Step-by-step explanation:
Simple addition with decimals. If you have a whole number like 5, with a decimal like 0.07, 5+0.07 would be 5.07. 5 would take the spot of 0 in the ones place and .07 would remain. If you have 0.10+0.8, it would be 0.9 as your answer since we make 0.8 to 0.80 or 0.10 to 0.1 and add the two together. Hope this helped!
