Question

Solve ................​

Answer 1

simple bro 1)

$2 \div \sqrt{5}$

on rationalising .

$2 \sqrt{5} \div 5$

$(2 \times 2.236) \div 5$

$0.894$

2)

$(2 - \sqrt{3} ) \div \sqrt{3}$

mutiply numerator and denominator by √3 then

$(2 \sqrt{3 } - 3) \div 3$

$(2 \times 1.732 - 3) \div 3 = 0.464 \div 3 = 0.154$

3)

$(\sqrt{10} - \sqrt{5} ) \div \sqrt{2} =( 3.162 - 2.236) \div 1.414$

$0.926 \div 1.14 = 0.654$

i hope my answer help you ✌️ ✌️❤️
