​

Answer 1

Answer:

The answer of this question is 57 .149048289

Answer 2

Answer:

10

Explanation:

$\frac{7.63 \times 7.63 - 2.37 \times 2.37}{5.26} = \frac{ {7.63}^{2} - {2.37}^{2} }{5.26}$

[using identity a²-b²= (a+b)(a-b)]

$= \frac{(7.63 + 2.37)(7.63 - 2.37)}{5.26}$

$= \frac{10 \times 5.26}{5.26}$

= 10

Hope It Helps :)
