Final answer:
To solve the expression 64.3-3x2 to the third power divided by 2, simplify inside the parentheses, raise the result to the third power, and divide by 2.
Step-by-step explanation:
To solve the expression 64.3-3x2 to the third power divided by 2, we need to follow the order of operations, which is parentheses, exponents, multiplication, and division from left to right.
First, let's simplify the expression inside the parentheses: 64.3-3x2 = 64.3-6 = 58.3
Next, we raise the result to the third power: 58.3^3 = 19671.327
Finally, we divide the result by 2: 19671.327 / 2 = 9835.6635
