Q. Find the value of 7−(12)37-(\frac{1}{2})^3
  1. Identify expression: Identify the expression to be simplified. 7−(12)37 - (\frac{1}{2})^3
  2. Calculate cube: Calculate the cube of one-half.\newline(12)3=12×12×12=18(\frac{1}{2})^3 = \frac{1}{2} \times \frac{1}{2} \times \frac{1}{2} = \frac{1}{8}
  3. Subtract from 77: Subtract the result from 77.\newline7−18=568−18=5587 - \frac{1}{8} = \frac{56}{8} - \frac{1}{8} = \frac{55}{8}
