Questions & Step-by-Step Solutions

What is the value of the expression 2^3 + 3^2 - 4? (2021)
  • Step 1: Calculate 2 raised to the power of 3 (2^3). This means multiplying 2 by itself 3 times: 2 * 2 * 2 = 8.
  • Step 2: Calculate 3 raised to the power of 2 (3^2). This means multiplying 3 by itself 2 times: 3 * 3 = 9.
  • Step 3: Add the results from Step 1 and Step 2 together: 8 + 9 = 17.
  • Step 4: Subtract 4 from the result of Step 3: 17 - 4 = 13.
  • Step 5: The final answer is 13.
