For example, if scientists have to send a spacecraft to the moon, it should travel at least 240,000 miles, which is the distance between Earth and the Moon. Scientists and engineers often encounter very big or small numbers. When the exponent is negative, the value is always less than 1.Īny number raised to the power 0 is one, and ten is no exception. The value is a decimal point followed by as many zeros as one less than the exponent and a 1. In general, we can write the value in decimals by observing the exponent. When the exponent is negative, we can apply the rules of exponent, x -a = 1/x a, and find the value.įor example, 10 -4 = 1/10 4 = 1/10000 = 0.0001 The number of zeros in the product is equal to the exponent. When the exponent is positive, we can write the power in the expanded form and find the product.įor example, 10 4 = 10 × 10 × 10 × 10 = 10,000. The exponent of a power of ten can be a positive or negative integer. The exponent of the power tells us how many times the number is multiplied to itself.įor example, when the exponent is 3, we multiply 10 by itself 3 times.ġ0 3 = 10 × 10 × 10, this is also called the expanded form of the power.
