Solution 1

To rationalize the denominator of the expression 103\frac{10}{\sqrt{3}}, we need to multiply both the numerator and the denominator by the conjugate of the denominator.

The conjugate of 3\sqrt{3} is also 3\sqrt{3}, because the conjugate of a single term is just itself.

So, we multiply both the numerator and the denominator by 3\sqrt{3} to get:

103\frac{10}{\sqrt{3}} * 33\frac{\sqrt{3}}{\sqrt{3}} = 1033\frac{10\sqrt{3}}{3}

So, the form of 1 that we can use to rationalize the denominator of the expression 103\frac{10}{\sqrt{3}} is 33\frac{\sqrt{3}}{\sqrt{3}}.

Solution 2

To rationalize the denominator of the expression 103\frac{10}{\sqrt{3}}, we need to multiply both the numerator and the denominator by a form of 1 that will eliminate the square root in the denominator.

The form of 1 we can use is 3/3\sqrt{3}/\sqrt{3}, because 33=3\sqrt{3} * \sqrt{3} = 3, which is a rational number.

So, we multiply the numerator and the denominator by 3\sqrt{3}:

10333=1033\frac{10}{\sqrt{3}} * \frac{\sqrt{3}}{\sqrt{3}} = \frac{10\sqrt{3}}{3}

So, the rationalized form of 103\frac{10}{\sqrt{3}} is 1033\frac{10\sqrt{3}}{3}.
