6²-3×2³

To solve the expression \(6^2 - 3 \times 2^3\), we can follow the order of operations (PEMDAS/BODMAS: Parentheses/Brackets, Exponents/Orders, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)).

1. Calculate the exponentials:

   • \(6^2 = 36\)
   • \(2^3 = 8\)

2. Substitute back into the expression: \[ 36 - 3 \times 8 \]

3. Calculate the multiplication: \[ 3 \times 8 = 24 \]

4. Now substitute that back into the expression: \[ 36 - 24 \]

5. Finally, perform the subtraction: \[ 36 - 24 = 12 \]

Therefore, \(6^2 - 3 \times 2^3 = 12\).
