What does a negative exponent mean?
As the page explains, a negative exponent just means “the multiplicative inverse of the base raised to the positive opposite of the power”.

What does 10 to the power of negative 3 mean?
A number which is some power of 1/10 can also be expressed easily in scientific notation. By definition, 1/10 = 10-1 (“ten to the minus one power”) More generally, the expression “10-n” (where n is a whole number) means ( 1/10 )n. Thus 10-3 = ( 1 / 10 )3 = 1 / ( 10 x 10 x 10) = 1/1000.
What does 10 to the negative 12 mean?
10 to the negative 12th power = The absolute value of the exponent of the number -12, 12, denotes how many times to multiply the base (10), and the power’s minus sign stands for reciprocal. Thus, we can answer what is 10 to the negative 12th power as. 10 to the power of minus 12 = 10-12 = 1 / 100 0000000000.
How is a negative exponent different from a positive exponent?
A positive exponent tells us how many times to multiply a base number, and a negative exponent tells us how many times to divide a base number. We can rewrite negative exponents like x⁻ⁿ as 1 / xⁿ. For example, 2⁻⁴ = 1 / (2⁴) = 1/16.
What is the formula for the law of negative exponents?
The law of negative exponents states that, when a number is raised to a negative exponent, we divide 1 by the base raised to a positive exponent. The general formula of this rule is: a -m = 1/a m and (a/b) -n = (b/a) n .
What do you call the exponent of a number?
Exponents are also called Powers or Indices. Let us first look at what an “exponent” is: The exponent of a number says how many times to use. the number in a multiplication.
