Answer:
So the answer for your question is Sarah is correct because square root 2 is irrational:)
Step-by-step explanation:
Rational numbers are numbers that can be expressed as a fraction or part of a whole number. (examples: -7, 2/3, 3.75) Irrational numbers are numbers that cannot be expressed as a fraction or ratio of two integers.
√ means square root. Square root means a number which produces a specified quantity when multiplied by itself. SO for example 7 is a square root of 49...
Example of another irrational and rational number: 74 is rational. Irrational number would be 3.14:)
