Questions & Step-by-Step Solutions

If a = 2 and b = 3, what is the value of (a + b)²?
  • Step 1: Identify the values of a and b. Here, a = 2 and b = 3.
  • Step 2: Add the values of a and b together. So, calculate (a + b) = (2 + 3).
  • Step 3: Perform the addition. 2 + 3 equals 5.
  • Step 4: Now, we need to square the result from Step 3. So, calculate (5)².
  • Step 5: Perform the squaring. 5 squared (5²) equals 25.
  • Order of Operations – Understanding the correct sequence to perform mathematical operations, particularly the importance of parentheses and exponents.
  • Algebraic Expressions – Evaluating expressions by substituting values for variables.
