Answer

The expression \(9^{2} \div 3^{2} \cdot 2 + 7 \cdot 6\) equals **60**.

Solution

Let's evaluate the expression step by step to ensure accuracy: \[ 9^{2} \div 3^{2} \cdot 2 + 7 \cdot 6 \] **Step 1: Calculate the exponents** \[ 9^{2} = 81 \\ 3^{2} = 9 \] So, the expression becomes: \[ 81 \div 9 \cdot 2 + 7 \cdot 6 \] **Step 2: Perform the division and multiplication from left to right** \[ 81 \div 9 = 9 \\ 9 \cdot 2 = 18 \\ 7 \cdot 6 = 42 \] Now, the expression is: \[ 18 + 42 \] **Step 3: Add the remaining terms** \[ 18 + 42 = 60 \] **Final Answer:** \(60\) It appears there was a mistake in the final step of your calculation. The correct result of the expression \(9^{2} \div 3^{2} \cdot 2 + 7 \cdot 6\) is **60**, not 175.

Extra Insights

Let's unravel this math problem! First, we can indeed break it down step by step. To clarify, \( 9^{2} \div 3^{2} \) equals \( 9 \) because \( 81 \div 9 = 9 \). Then, you multiply that \( 9 \) by \( 2 \) to get \( 18 \). Moving on to the \( 7 \cdot 6 \), that's \( 42 \). So when you add \( 18 + 42 \), you end up with a well-deserved \( 60 \), not \( 175 \). Now, if you're ever trying to avoid mistakes in similar problems, remember the order of operations: Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right). It’s a classic formula! Double-checking your work at each step can save you from unpleasant surprises like the mix-up in this problem. Who knows, it might even make you the math whiz among your friends!
