Question

Rationalise the denominator of each of the following

Answer 1

Step-by-step explanation:

$1 \times (2 \sqrt{5} + \sqrt{3} ) \div (2 \sqrt{5} - \sqrt{3} ) \times(2 \sqrt{5} + \sqrt{3} )$

$(2 \sqrt{5} + \sqrt{3} ) \div (20 - 3)$

$2 \sqrt{5} + \sqrt{3} \div 17$

hence denominator has rationalized
