You know we also know how to represent $\pi$ exactly right?It is my belief that what I said has a lot to do with math.
My reasoning for using Imperfect squares is that although irrational square roots cannot be written as fractions, we can still write them exactly.
For example, suppose you need to find √18. You know there is no whole number squared that equals 18, so √18 is an irrational number. The value is between √16=4 and √25=5. However, we need to find the exact value of √18
We begin by writing the prime factorization of the square root of 18.. √18=√9×2=√9×√2.
√9=3 but √2 does not have a whole number value. Therefore, the exact value of √18 is 3√2. A value that represents itself in its entirety. That is different from ≈ "approximately equal to"
