This answer was rated:

★★★★★

Biologists have found that the weight W of a bird and the length L of its wing span are related by L=kW^1/3, where k is a constant. The W(kilograms) is 0.1 and the L (meters) is 0.427. approximate the value of K. Then - find the wing span of a 0.90-kilogram bird using L=0.92(0.90)^1/3

You helped me yesterday by telling me of using the Excell cell to get a solution to (0.1)^1/3. which I did , HOW did we get the 0.888????? I get a number like .276.......
