Full solution

Q. (10×9.258,484)(9.619,98)2102×(101) \sqrt{\frac{(10 \times 9.258,484)-(9.619,98)^{2}}{10^{2} \times(10-1)}}
  1. Correct Notation: First, we need to correct the notation of the numbers involved in the expression. The commas should be decimal points. The expression should be written as: ((10×9.258484)(9.61998)2)/(102×(101))\sqrt{\left(\left(10 \times 9.258484\right) - \left(9.61998\right)^2\right) / \left(10^2 \times \left(10 - 1\right)\right)}
  2. Calculate Product: Now, let's calculate the term 10×9.25848410 \times 9.258484:10×9.258484=92.5848410 \times 9.258484 = 92.58484
  3. Calculate Square: Next, we calculate the square of 9.619989.61998: \newline(9.61998)2=92.5439604004(9.61998)^2 = 92.5439604004
  4. Subtract Square: Subtract the square of 9.619989.61998 from the product of 1010 and 9.2584849.258484: \newline92.5848492.5439604004=0.040879599692.58484 - 92.5439604004 = 0.0408795996
  5. Calculate Denominator: Now, calculate the denominator, which is the product of 1010 squared and 99: 102×(101)=100×9=90010^2 \times (10 - 1) = 100 \times 9 = 900
  6. Divide by Denominator: Divide the difference obtained earlier by the denominator: 0.0408795996/900=0.00004542177733330.0408795996 / 900 = 0.0000454217773333
  7. Calculate Square Root: Finally, take the square root of the quotient: 0.00004542177733330.006738\sqrt{0.0000454217773333} \approx 0.006738
  8. Final Value: We have now found the value of the given expression.
