Study Notes

Rational Numbers

  • The problem involves a combined exercise of rational numbers.
  • It includes operations like square root, division, and addition with negative numbers.
  • Steps to solve the combined exercise:
    • Calculate the square root of 5/64, which is √5/8.
    • Divide √5/8 by -1/2, which results in -√5/4.
    • Add -√5/4 and -2/3, after finding the common denominator of 12, resulting in (-3√5 -8)/12.
  • The final answer, in its simplest form, is (-√5 - 8/3)/12.
