How do you simplify the square root of 73?

1 AnswerSo √24=√23⋅3=√22⋅2⋅3=√22⋅√2⋅√3.⇒√24=2⋅√2⋅√3=2√6.Using our knowledge of: √a⋅b=√a⋅√b.√73=√1⋅√73=√73..

How do you simplify radical 65?

1 Answer. 65=5⋅13 has no square factors, so √65 is the simplest form.

Can square roots be rational?

Oh no, there is always an odd exponent. So it could not have been made by squaring a rational number! This means that the value that was squared to make 2 (ie the square root of 2) cannot be a rational number. In other words, the square root of 2 is irrational.

Is 2 root 5 rational or irrational?
