The "Power of Ten" is a concept that illustrates the scale of magnitude by increasing or decreasing a quantity by factors of ten. It is often represented in scientific notation, where a number is expressed as a base multiplied by ten raised to an exponent. For example, 10^2 equals 100, while 10^-2 equals 0.01. This method helps in understanding very large or very small numbers easily. This concept is widely used in various fields, including mathematics, science, and engineering. It allows for quick comparisons and calculations, making it easier to grasp the vast differences in size, such as the distance between planets or the size of microorganisms.
