We can use the power of 10 as a tool in making quick estimations when we do not need or care for the exact value of a number.For example, the diameter of an atom is approximately 10 to the power of negative 12 meters.The height of a tree is approximately 10 to the power of one meter.The diameter of the Earth is approximately 10 to the power of seven meters.The ability to use the power of 10 as an estimation tool can come in handy every now and again,like when you're trying to guess the number of M&M's in a jar,but is also an essential skill in math and science,especially when dealing with what are known as Fermi problems.
