Question

Jessica evaluates √2 on her calculator which

shows a value of 1.4142136.
She then writes √/2 =1.4142136.
Is she correct explain

Answer 1

Generally, one should not write down values such as this directly from a calculator. √2 is an irrational number, which means that instead of writing it as a terminating decimal, it is best to write it in its exact form (√2) to ensure accuracy for further calculations.
