Geographers find that the length of a river varies with the 0.6 power of the river basin. The Rio Grande is 3034 kilometers long, and the basin is 500,000 square kilometers. Find the particular equation and use it to predict the river basin of the Nile (to the nearest hundred thousand), which at 6700 kilometers is the longest river in the world. (Note: this might trouble you at first. Here's a hint: taking the square root of a number is the same as raising it to the % power)
