what's the answer to this equation?
5+4 times (8-6) to the second power.
(9 * 2)^2 = 324
324
To solve this equation, we need to follow a specific order of operations known as PEMDAS (Parentheses, Exponents, Multiplication and Division - from left to right, Addition and Subtraction - from left to right).
The equation is: 5 + 4 * (8 - 6)²
1. First, we start by simplifying what's inside the parentheses: 8 - 6 equals 2.
The equation becomes: 5 + 4 * 2²
2. Next, we solve the exponent: 2² equals 2 * 2, which equals 4.
The equation becomes: 5 + 4 * 4
3. Now we can perform the multiplication: 4 * 4 equals 16.
The equation becomes: 5 + 16
4. Finally, we perform the addition: 5 + 16 equals 21.
Therefore, the answer to the equation 5 + 4 * (8 - 6)² is 21.
