Solving the Equation: (4x5)^2 - 6 + 3
This article will break down the steps to solve the equation (4x5)^2 - 6 + 3.
Order of Operations (PEMDAS/BODMAS)
To solve this equation, we'll use the order of operations, often remembered by the acronyms PEMDAS or BODMAS.
- Parentheses/ Brackets
- Exponents/ Orders
- Multiplication and Division (from left to right)
- Addition and Subtraction (from left to right)
Step-by-Step Solution
- Parentheses/Brackets: First, we need to solve the expression inside the parentheses (4x5), which equals 20.
- Exponents/Orders: Next, we need to square 20 (20^2), which equals 400.
- Addition and Subtraction (from left to right): Now, we have 400 - 6 + 3.
- 400 - 6 = 394
- 394 + 3 = 397
Final Answer
Therefore, (4x5)^2 - 6 + 3 = 397.
