Answer: 
Step-by-step explanation:
This could be written in index form as :
By laws of indices , we will equate their power , that is :
Expanding , we have :
factorising the Quadratic equation , we have :
Therefore:
or 
'Pi' is an irrational number. It can never be completely written with digits.
Here are the first 15 decimal places: 3.14159 26535 89792
A supercomputer lab in Japan has calculated <u>4 trillion</u> digits of pi,
and it still doesn't end.
With higher mathematics, it's possible to <u>prove</u> that pi never ends.
So, no matter how many digits somebody gives you for pi, there are
still an infinite number more after those.
You take the amount paid and divide it by the amount of cheese. So 10.50 divided by 2.5 equals 4.2 and 12.60 divided by 3 equals 4.2 meaning that one pound of cheese costs $4.20

This is the farthest it can be simplified, hope I helped! </span></span>
X^2 + y^2 - 2x + 2y - 1 = 0
(x^2 - 2x) + (y^2 + 2y) - 1 = 0
(x^2 - 2x + 1) + (y^2 + 2y + 1) - 1 - 1 - 1 = 0
(x - 1)^2 + (y + 1)^2 - 3 = 0
(x - 1)^2 + (y + 1)^2 = 3
