Answer:
Hence the simplification of
is 
Step-by-step explanation:
<em>" Simplification is the process of replacing a mathematical expression by an equivalent one, that is simpler (usually shorter), </em>
<em>for example</em><em>: Simplification of a fraction to an irreducible fraction ". </em>
Here we are given a fraction as:

As both the numerator and denominator are divisible by a factor of 3 hence we take out the common factor and obtain the reduced fraction which is further irreducible.
As 66=3×22 and 81=3×27
Hence 
Hence the simplification of
is 
Answer:
is
times greater than
.
Step-by-step explanation:
We are given two numbers.
First number :
.
Second number :
.
In order to find how many times
is greater than
, we need to divide first number by second number.
Therefore,
÷ 
or 
First we would divide 6 by 5.
On dividing 6 by 5, we get 1.2.
Now, we would divide 10^-5 by 10^-9.
In order to divide them, we can apply quotient rule of exponents
.
We get
.
Therefore,
= 
So, we could say finally
is
times greater than
.
Answer:
12
Step-by-step explanation: If you made x, 4 and y, 5 then all equations would make sense if you change the letters to numbers.
IF
(3*4)+(4*10)=52
and
(5*4)+10=30
then
<h2>
(8*4)-2*10=<u><em>
12</em></u></h2><h2 />
Simply cross multiply and simplify to get a = 11
Hope this helped!! xx
