Question

7+2√10ka vargmool kitna hoga

Answer 1

varmool5+varmool2 it's your answer

Answer 2

=> 7 + 2√10


Splitting 7 into two parts or numbers.
7 = 5 + 2


=> 5 + 2 + 2√10

=> ( √5 )² + ( √2 )² + 2( √2 × √5 )



As we a² + b² + 2ab is the expanded form of ( a + b )² , writting ( √5 )² + ( √2 )² + 2(√2 × √5 ) in the form of ( a + b )²



=> ( √5 + √2 )²


square root of any number is the number with ½ in its power.


$( \sqrt{5} + \sqrt{2} ) {}^{2 \times \frac{1}{2} } \\ \\ \\ ( \sqrt{5} + \sqrt{2} ) {}^{1} \\ \\ \\ \sqrt{5} + \sqrt{2}$



Isliye ( 5 + 2 + 2√10 ) ka vargmool √5 + √2 hoga.
