Question

the question no. 7 please solve it​

Answer 1

Answer:

Step-by-step explanation:

There is a formula-.(a+b)(a-b)=a²-b²

So, (5+√11)(5-√11)

= 5² +√11²

=25+11

=36

So Reena distributed 36 chocolates.

Answer 2

Answer:

here's your solution↓

Sol:

1) [ 5 + √(11) ] [ 5 - √( 11) ]

= ( 5^2 ) ( √(11)^2 )...... {by converse of formula (a^2 + b^2)}

= 25 × 11

= 275 chocolate s

Ans: Total no. of chocolate distributed by her =275
