Question

(4+√5) (√3+√7). solve​

Answer 1

SOLUTION :-----

$(4 + \sqrt{5})( \sqrt{3} + \sqrt{7} )$

$= 4 \sqrt{3} + 4 \sqrt{7} + \sqrt{5} \sqrt{3} + \sqrt{5} \sqrt{7}$

Now here ,

$4 \sqrt{3} + 4 \sqrt{7} = 17.511$

$\sqrt{5} \sqrt{3} \ + \sqrt{5 } \sqrt{7} = 9.789$

Now add the both values..

17.511+9.789 = 27.300 is the answer
