simplify​

Answer 1

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
