Answer 2

To find the value of the expression 64x^3 - 96x^2 + 48x - 8 when x = 0.75, we can substitute the value of x into the expression and perform the calculation.

Let's substitute x = 0.75 into the expression:

64(0.75)^3 - 96(0.75)^2 + 48(0.75) - 8

Now, let's calculate the result:

64(0.75)^3 = 64(0.421875) = 27

96(0.75)^2 = 96(0.5625) = 54

48(0.75) = 36

Putting it all together:

27 - 54 + 36 - 8 = 1

Therefore, when x = 0.75, the expression 64x^3 - 96x^2 + 48x - 8 evaluates to 1.
