Questions & Step-by-Step Solutions

Find the value of 3^3 - 2^3. (2020)
  • Step 1: Calculate 3 raised to the power of 3 (3^3). This means multiplying 3 by itself three times: 3 * 3 * 3.
  • Step 2: Perform the multiplication: 3 * 3 = 9, then 9 * 3 = 27. So, 3^3 = 27.
  • Step 3: Calculate 2 raised to the power of 3 (2^3). This means multiplying 2 by itself three times: 2 * 2 * 2.
  • Step 4: Perform the multiplication: 2 * 2 = 4, then 4 * 2 = 8. So, 2^3 = 8.
  • Step 5: Subtract the result of 2^3 from the result of 3^3: 27 - 8.
  • Step 6: Perform the subtraction: 27 - 8 = 19.
  • Exponents – Understanding how to calculate powers of numbers.
  • Basic Arithmetic – Performing subtraction after evaluating the powers.
