Answer. Thus the denominator of 7/(5√3-5√2) is 25.

Usually, the negative sign is placed in front of the fraction, but you will sometimes see a fraction with a negative numerator or denominator. Remember that fractions represent division. The fraction −13 could be the result of dividing −13 , a negative by a positive, or of dividing 1−3 , a positive by a negative.

If there is one minus sign in a simple fraction, the value of the fraction will be negative. , the value of the fraction is -. 75.

So, in order to rationalize the denominator, we need to get rid of all radicals that are in the denominator.

1. Step 1: Multiply numerator and denominator by a radical that will get rid of the radical in the denominator.
2. Step 2: Make sure all radicals are simplified.
3. Step 3: Simplify the fraction if needed.

Denominator after rationalising =70.

Answer. Therefore the denominator is 25.

Surds are the square roots (√) of numbers that cannot be simplified into a whole or rational number. It cannot be accurately represented in a fraction. In other words, a surd is a root of the whole number that has an irrational value.
