Answer:
examples of irrational numbers is pi 3.1415, square root of 2,
Step-by-step explanation:
In mathematics, the irrational numbers are all the real numbers which are not rational numbers. That is, irrational numbers cannot be expressed as the ratio of two integers. ... In the case of irrational numbers, the decimal expansion does not terminate, nor end with a repeating sequence.
![3x^{2} +1=28](https://tex.z-dn.net/?f=3x%5E%7B2%7D%20%2B1%3D28)
Step 1 : subtract 1 from both sides
![3x^{2} =27](https://tex.z-dn.net/?f=3x%5E%7B2%7D%20%3D27)
Step 2 : Divide both sides by 3
![\frac{\frac{3x^{2} }{3} }{\frac{27}{3} }](https://tex.z-dn.net/?f=%5Cfrac%7B%5Cfrac%7B3x%5E%7B2%7D%20%7D%7B3%7D%20%7D%7B%5Cfrac%7B27%7D%7B3%7D%20%7D)
![x^{2} = 9](https://tex.z-dn.net/?f=x%5E%7B2%7D%20%3D%209)
Step 3 : Find the square root of 9
![\sqrt{9} = 3](https://tex.z-dn.net/?f=%5Csqrt%7B9%7D%20%3D%203)
x= (-3,3)
remember negative × negative = positive
False if 0 is a whole number
