First, ignore the decimal points of the two values and multiply them

$0.009$ $0.009$ $=$ $=$ $9$ $9$

$8 \times 9$ $8xx9$ $=$ $=$ $72$ $72$

Next, count how many place values from the decimal point to the right of the two factors.

$0.009 =$ $0.009 =$ $3 places$ $3 \text(places)$

There is a total of $3$ $3$ place value movements to the right of the decimal point.

Finally, get the final product by moving the decimal point of the initial product $3$ $3$ places to the left.

Therefore, the final product is $0.072$ $0.072$ .

First, ignore the decimal points of the two values and multiply them

$0.04$ $0.04$ $=$ $=$ $4$ $4$

$70 \times 4$ $70xx4$ $=$ $=$ $280$ $280$

Next, count how many place values from the decimal point to the right of the two factors.

$0.04 =$ $0.04 =$ $2 places$ $2 \text(places)$

There is a total of $2$ $2$ place value movements to the right of the decimal point.

Finally, get the final product by moving the decimal point of the initial product $2$ $2$ places to the left.

Therefore, the final product is $2.8$ $2.8$ .
