Answer:
-1
Step-by-step explanation:
We need to simplify the given expression . The given expression is , 
 
 
Here we can see that the power of the both exponent is same that is (2n+1) . Recall the property of exponents , 
 
 
Using this property , we have ,
 
 
This can be written as ,
 
 
Simplifying using ( a+b)(a-b) = a² - b² , 
 
 
Subtracting the numbers inside the brackets ,
 
 
Now we know that every odd number is in the form of 2n -1 , where n is any integer. Therefore , the <u>power is odd</u> .
 Since the base is (-1) , for even power it is 1 and for odd power it is -1 . Therefore the final answer is , 
 
 
<u>Hence </u><u>the</u><u> </u><u>required</u><u> answer</u><u> is</u><u> </u><u>(</u><u>-</u><u>1</u><u>)</u><u> </u><u>.</u>

Answer:
Step-by-step explanation:
hello : 
if : r  the radius  ( r ≠0)
the circumference is :  2πr
the area is : πr²
so : πr² = 2πr 
simplify by : r π  you have : r=2
