Question

Simplify (3+√7) (2+√5)

Answer 1

( 3+√7)(2+√5)

= 3 (2+√5) +√7(2+√5)

= 6+3√5 +2√7+√35

Answer 2

Answer:

$(3+\sqrt{7} )(2+\sqrt{5} )=6+3\sqrt{5}+2\sqrt{7}+\sqrt{35}$

Step-by-step explanation:

Given: $(3+\sqrt{7} )(2+\sqrt{5} )$.

To simplify.

Using distributive law it can be written as:

$(3+\sqrt{7} )(2+\sqrt{5} )=3(2+\sqrt{5} )+\sqrt{7}(2+\sqrt{5} )$

                            $=6+3\sqrt{5}+2\sqrt{7}+\sqrt{35}$

Hence, $(3+\sqrt{7} )(2+\sqrt{5} )=6+3\sqrt{5}+2\sqrt{7}+\sqrt{35}$.
