Question

Which number is an irrational number? 3 3/4 3 3/4 √64 √, 64 √91 √, 91 10.25

Answer 1

`√(91)` is irrational

Explanation:

A rational number is a number that can be written as a ratio. Any whole number is rational number because it can be turned into a ratio.

The
`√(91)` is irrational.

3 (or 3/1) is rational.

3/4 is rational

`√(64)` = 8 and thus, is rational.

`√(91)` = 9.539392014...... and is irrational

10.25 can be written as 41/4 so it's also rational.

This is based on my assumption you mistyped the 2 with the commas.
