The pennies placed on the squares D, E, F, G, and H will be 8, 16, 32, 64, and 128 pennies.
Given
There are 8 rows and 8 columns, which means 64 squares on a chessboard.
We are placing 1 penny on Row 1 Column A, 2 pennies on Row 1 Column B, 4 pennies on Row 1 Column C, and so on.
<h3>What is the matrix?</h3>A matrix (plural matrices) is a rectangular array or table of numbers, symbols, or expressions, arranged in rows and columns, which is used to represent a mathematical object or a property of such an object.
So, we are increasing the number of pennies twice the amount of the previous square.
So, the pennies on next squares will be,
Therefore, the pennies placed on the squares D, E, F, G, and H will be 8, 16, 32, 64, and 128 pennies.
