We are to round the numbers to nearest tens and estimate the product.
[tex]37.89\cdot41[/tex]
Let us roung up the numbers to the nearest tens first.
[tex]\begin{gathered} 37.89\approx40(nearest\text{ tens)} \\ 41\approx40(nearest\text{ tens)} \end{gathered}[/tex]
Let us now find the product of the numbers
[tex]\begin{gathered} 40\cdot40=40\times40=1600 \\ 40\cdot40=1600 \end{gathered}[/tex]
Hence, the answer is
[tex]40\cdot40=1600[/tex]
