Step-by-step explanation:

$(5+√7)(2+√3)$

Apply FOIL method...

$= > 5 \times 2 + 5 \sqrt{3} + \sqrt{7} \times 2 + \sqrt{7} \sqrt{3}$

$= > 5 \times 2 + 5 \sqrt{3} + 2 \sqrt{7} + \sqrt{7} \sqrt{3}$

Simplify...

$= > 10 + 5 \sqrt{3} + 2 \sqrt{7} + \sqrt{21}$

Answer 2

Answer:

Step-by-step explanation:

(5+√7)(2+√3)​

= (5)*(2) + (5)*(√3) + (√7)*(2) + (√7)*(√3)

= 10 + 5√3 + 2√7 + √21  

= 28.534                                    ( corrected upto 3 decimal places )
