Numbers expressed using exponents are called powers. When writing a number expressed as an exponent, the number is called the base. For example, in 23 two is the base.

510 can be expressed as 5.1 × 102

Anything to the power of a negative number is equal to one divided that "anything" raised to the positive value of the exponent. For example:a-b = 1/ abSo you can think of this by expressing the number as a fraction. Consider, what is 0.1 as a fraction? The answer is 1/10. This means that when expressed as an exponent, it would be 10-1.

Yes, you can, but it starts getting complicated. You can, for example have a number raised to an exponent that is itself a number raised to an exponent, or you can have a number raised to an exponent and the result raised to another exponent.

Scientific Notation is expressed by using a number, using an exponent as a number (usually a decimal) multiplied by a 10, and an exponent (the number on the exponent is the number of zeros the number has).Example: 120,000,000 in scientific notation is 1.2 X 107

Every number can be expressed using an exponent. You select a base, b, which should be a positive real number. Suppose the number is x.If this number is negative, then its exponent form will have a negative sign before it.The absolute value of the number is converted to the exponent form by solving x = b^y where y is the exponent. However, you need to know about logarithms before you can do that (and this question suggests that you have not yet progressed to that level of mathematics).
