To simplify the expression (2–√)^3⋅2−^1/2 using exponent properties, we can apply the rule that states (a^m)^n = a^(m*n).

First, let's simplify (2–√)^3:

(2–√)^3 = (2–√)(2–√)(2–√)

Using the distributive property, we can expand this expression:

= (2–√) * (2–√ * 2–√)
= (2–√)*(2–√ * 2)
= (2–√)*(2–2√)
= (2–√)*(2 – 2√ + 2√ – 2) (using the distributive property again)
= (2–√)*(0)
= 0

Now let's simplify 2^(-1/2):

2^(-1/2) = 1/(2^(1/2)) = 1/√2

Therefore, the expression (2–√)^3⋅2−^1/2 simplifies to:

0 * 1/√2 = 0

So the correct response is 0.
