Answer:
Proved
Step-by-step explanation:
Given
Integers: a and b
Where 
Required
Show that 
We start by writing out the given expression

Then, take nth root of both sides

For instance:
Let a = 2, b = 2 and n = 4
First
Since 
Then

<em>This is so for all positive values of a,b and n where a < b</em>
Answer:
x = -7
Step-by-step explanation:
-2x - 10 = 4
-2x = 14 | Add 10 to both sides
x = -7 | Divide both sides by -2
As it has been given that
,
.
We need to find the value of the following:
(i)
, substituting the value of 'x' and 'y' in the expression, we get:


So, 
(ii)
, substituting the value of 'x' and 'y' in the expression, we get:


So, 
(iii)
, we need to substitute the value of 'x' and 'y' in the expression, for this, we can use distributive property of multiplication that says,

Using the distributive property of multiplication:


Now, we know that 
We get, 

Therefore,
=
.
(iv) We have,
, we need to substitute the value of 'x' and 'y' in the expression, we get:

Again, we can use distributive property of multiplication that says,

So,



since, 
we get,


Therefore,
