Answer :

To determine the product of [tex]\(0.54\)[/tex] and [tex]\(0.8\)[/tex], we multiply the two numbers together.

[tex]\[ 0.54 \times 0.8 = 0.43200000000000005 \][/tex]

When rounding to a reasonable number of decimal places (typically two or three for such precision), the product is:

[tex]\[ 0.432 \][/tex]

Thus, considering the options given:

A. 0.432
B. 4.32
C. 43.2
