To tackle these multiplication problems, let's first break each down. For \( 354 \times 781 \): A good estimate would be rounding to \( 350 \times 780 \), which equals \( 273,000 \). The exact product is \( 276,834 \), which is reasonable as it aligns closely with our estimate. Next, for \( 4,029 \cdot 276 \): Rounding to \( 4,000 \times 300 \) gives us \( 1,200,000 \). The exact answer is \( 1,111,984 \), a tad less than our estimate, but reasonable given the rounding choices. Lastly, for \( 950 \times 326 \): Rounding to \( 1,000 \times 300 \) yields \( 300,000 \). The exact product is \( 309,700 \), which is again reasonable as it stays in line with our estimate. Happy calculating!
