Answer 2

Answer:

32.34

Step-by-step explanation:

Expression : $(5+\sqrt{7})(2+\sqrt{5})$

Solution:

$(5+\sqrt{7})(2+\sqrt{5})$

$5(2+\sqrt{5})+\sqrt{7}(2+\sqrt{5})$

$10+5\sqrt{5}+2\sqrt{7}+\sqrt{35}$

Since value of $\sqrt{5} = 2.23$

Value of $\sqrt{7} = 2.64$

Value of $\sqrt{35} = 5.91$

Substitute the values

$10+5(2.23)+2(2.64)+5.91$

$32.34$

Hence the simplified value of given expression is 32.34
