To simplify −4 + 7 • 3² using the order of operations (PEMDAS):

1. **Exponents**: Calculate \(3^2 = 9\).
2. **Multiplication**: Compute \(7 \cdot 9 = 63\).
3. **Addition/Subtraction**: Perform \(-4 + 63 = 59\).

The result is **59**, corresponding to option **D**.

GPT-4o To simplify the expression −4 + 7 • 3^2, follow the order of operations (PEMDAS/BODMAS):

1. **Parentheses/Brackets**: There are none in this expression.
2. **Exponents/Orders**: Calculate the exponent first.
\( 3^2 = 9 \)

So the expression becomes:
\( −4 + 7 • 9 \)

3. **Multiplication/Division**: Perform the multiplication next.
\( 7 • 9 = 63 \)

So the expression now is:
\( −4 + 63 \)

4. **Addition/Subtraction**: Finally, perform the addition.
\( −4 + 63 = 59 \)

Therefore, the simplified result is:

minimax To simplify the expression −4 + 7 • 3^2, we follow the order of operations, which is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). This is often abbreviated as PEMDAS.

First, we calculate the exponent:
3^2 = 3 * 3 = 9

Next, we perform the multiplication:
7 • 9 = 63

Finally, we add and subtract from left to right:
−4 + 63 = 59

So the correct answer is:
D. 59

kimi First, let's simplify the expression step by step:

1. Calculate the exponentiation: \(3^2 = 9\).
2. Multiply by 7: \(7 \cdot 9 = 63\).
3. Add the negative 4: \(-4 + 63 = 59\).

So the correct answer is D. 59.

zhipu To simplify the expression \(-4 + 7 \cdot 3^2\), follow the order of operations (PEMDAS/BODMAS):

1. **Exponents first**: Calculate \(3^2\).
\[
3^2 = 9
\]

2. **Multiplication next**: Multiply \(7\) by \(9\).
\[
7 \cdot 9 = 63
\]

3. **Addition/Subtraction last**: Add \(-4\) to \(63\).
\[
-4 + 63 = 59
\]

So, the simplified expression is \(59\).
