Frank is investigating the numerical value of 2x · 2y when x and y are both integers. He makes the following two claims. Claim 1: When x and y are both negative integers, the value of 2x · 2y is always a non–whole number. For example, 2–1 · 2–1 = 0.25 and 2–5 · 2–1 = 0.015625. Claim 2: When only one of x or y is a negative integer, the value of 2x · 2y is always a non–whole number. For example, 22 · 2–3 = 0.5 and 2–5 · 21 = 0.0625. Which statement correctly classifies Frank's claims?
