Simplify \( \Large \frac{5.32 \times 56+5.32 \times 44 }{ \left(7.66^{2}\right)- \left(2.34\right)^{2} } \)

A) 7.2
B) 8.5
C) 10
D) 12

Correct Answer:



C) 10

Description for Correct answer:
\( \Large \frac{5.32 \times 56+5.32 \times 44 }{ \left(7.66^{2}\right)- \left(2.34\right)^{2} } \)

=\( \Large \frac{5.32 \left(56+44\right) }{ \left(7.66-2.34\right) \left(7.66+2.34\right) } \)

=\( \Large \frac{5.32 \left(100\right) }{ \left(5.32\right) \left(10\right) } \)

=\( \Large \frac{100}{10} \)=10
