The product of two positive integers is 2048 and one of them is twice the other. Then the smaller of the number is
32
Let the two numbers be x and 2x. Their product is x * 2x = 2048. So, 2x² = 2048, hence x² = 1024. Taking the square root of both sides, we get x = 32. Thus, the smaller number is 32.
