Question

Find the sum of 2root3 and 5root7​

Answer 1

$2 \sqrt{3} + 5 \sqrt{7}$

We know that;

$\color{blue}\sqrt{3} = 1.732$

And,

$\color{blue} \sqrt{7} = 2.645$

$\implies (2 \times 1.732) + (5 \times 2.645)$

$\implies 3.4 +13.0$

${\boxed{ \color{orange} \therefore 2 \sqrt{3} + 5 \sqrt{7} = 16.4}}$

HOPE THAT HELPS!!
