Evaluate (4² + 3) × √9: Order of Operations Practice

To solve the expression $(4^2+3)\times\sqrt{9}=$, we need to follow the order of operations, also known as PEMDAS/BODMAS (Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)).

• First, we deal with the exponent $4^2$, which means 4 raised to the power of 2. Calculate $4^2 = 16$.

• Next, we calculate the expression inside the parentheses: $(4^2+3)$. We already know $4^2 = 16$, so we add 3 to 16: $16 + 3 = 19$.

• Then, we find the square root of 9: $\sqrt{9} = 3$.

• Lastly, we perform the multiplication: $19 \times 3 = 57$.

Thus, the final result of the expression $(4^2+3)\times\sqrt{9}$ is 57.
