if a = -3, b = 2, c = 4, evaluate \(\frac{a^3 – b^3 – c^{\frac{1}{2}}}{b – a – c}\)

  • 37
  • \(\frac{-37}{5}\)
  • \(\frac{37}{5}\)
  • -37 checkmark

The correct answer is: D

Explanation

\(\frac{a^{3} - b^{3} - c^{\frac{1}{2}}}{b - a - c} = \frac{(-3)^{3} - (2)^{3} - 4^{\frac{1}{2}}}{2 - (-3) - 4}\)

= \(\frac{-37}{1} = -37\)
