![]() Another way to confirm this is using the property of exponents that states: We know that b -m 1/b m. Its a way to change division problems into multiplication problems. You use negative exponents as a way to combine expressions with the same base, whether the different factors are in the numerator or denominator. Well, if we have subtraction in the exponents, that means divide the powers, that must mean b to the 0. So this means that b to the -n, we can think of that as b to the 0- n. In general, -n, we can write that as 0- n. Note that a number to a negative exponent is not necessarily a negative number. We can see that this aligns with the formula above since 2 -5 1/2 5. If the negative exponent is in the denominator of a fraction, its expression gets moved to the numerator and the sign of the exponent is changed. Negative exponents are a way of writing powers of fractions or decimals without using a fraction or decimal. Any negative number can be written as zero minus the absolute value of that number. (yes i know im 8 years late, but hope this helps) ( 2 votes) Flag Show more. Its basically a negative number to a negative exponent makes a positive number and exponent. For example: 2 -5 1/2 × 1/2 × 1/2 × 1/2 × 1/2 1/32. Negative exponents put the exponentiated term in the denominator of a fraction and zero exponents just make the term equal to one. 2 months ago When a number is raised to a negative exponent, we invert the number to make the exponent positive. Secondly, take the reciprocal of the base and raise it to the positive exponent. In contrast, a negative integer exponent can be computed by multiplying by the reciprocal of the base, n times. ![]() Firstly, start with 1 and divide it by 2 the same number of times as the exponent. A number raised to a negative power is equal to one over the number raised to the positive opposite power. A base that has a negative exponent can be changed to a fraction. Negative exponents denote a reciprocal value. Think of it this way: in order to change the exponent in ?b^? are reciprocals. About Transcript Negative exponents can be rewritten in two ways.
