Question

= \frac{7(3352) - (393)(103)}{\sqrt{(7(24725) - (393)^2)(7(1933) - (103)^2)}}

Explanation:

Step1: Calculate numerator terms

$7(3352) = 23464$, $(393)(103)=40479$
Numerator: $23464 - 40479 = -17015$

Step2: Calculate first radical term

$7(24725)=173075$, $(393)^2=154449$
First term inside radical: $173075 - 154449 = 18626$

Step3: Calculate second radical term

$7(1933)=13531$, $(103)^2=10609$
Second term inside radical: $13531 - 10609 = 2922$

Step4: Multiply radical terms

$18626 \times 2922 = 54425172$

Step5: Compute square root

$\sqrt{54425172} \approx 7377.34$

Step6: Divide numerator by root

$\frac{-17015}{7377.34} \approx -2.306$

Answer:

$\approx -2.31$ (rounded to two decimal places)
