Answer 2

To evaluate the given expression at x = 1024, let's substitute the value of x into the expression:

Expression: x^(-0.2) - 0.25 / x^(-0.1) + 0.5

Substitute x = 1024:

Expression = 1024^(-0.2) - 0.25 / 1024^(-0.1) + 0.5

Now let's calculate the individual terms:

1. 1024^(-0.2): This is equivalent to raising 1024 to the power of -0.2.
2. 1024^(-0.1): This is equivalent to raising 1024 to the power of -0.1.

Then we'll perform the calculations and simplify the expression:

1. 1024^(-0.2) ≈ 0.6432188134
2. 1024^(-0.1) ≈ 0.8685113738

Now plug these values back into the original expression:

Expression ≈ 0.6432188134 - 0.25 / 0.8685113738 + 0.5

Calculate the division:

Expression ≈ 0.6432188134 - 0.287946625 + 0.5

Perform the addition and subtraction:

Expression ≈ 0.8552721884

Therefore, when x = 1024, the value of the given expression is approximately 0.8552721884.
