What is a rational number? It is a number that can be expressed as the ratio (fraction) of two integers.
sqrt%2849%2F100%29 Rewrite this as:
sqrt%2849%29%2Fsqrt%28100%29 Now take the square root of the numerator and the denominator.
7%2F10
Here you have the ratio of two integers, therefore, you have a rational number.
