It is -1/5

10-1 = 1/10 A number raised to a negative power is equal to the reciprocal of the number raised to the power. So a-b = (1/a)b = 1/ab

It's the inverse of the number raised to the power. 2 to the power of negative 3 would be 1/8th.1 over 25Improvement(shininggallade):When raising a whole number to a negative power, simply raise 5 to the second power, which is 25, and put a 1 over it. 5^-2=1/25 A more technical definition is to reverse the numerator and denominator and then apply the power. Remember 5 is the same as 5/1, so (5^-2)/1=1/(5^2)=1/25(The symbol for "to the power of" is "^" just to let you know.)

It is equivalent to 1 over 5 to the power of 5, or 1 over 3125.

No. A negative power simply indicates a reciprocal of the positive power. So 3-4 = 1/34 = 1/81 while (-2)-5 = 1/(-2)5 = 1/(-32) = -1/32

If you mean 5 to the power of -1 then it is 1/5

No, or more accurately "not necessarily".A negative to any even power is positive. -2, -4, -6 etc. are even, so a negative number raised to any of those powers will be positive.However, a negative number raised to an odd negative power (-1, -3, -5 etc.) will be negative.

That is the definition of negative powers.

0.2 or 1/5 :D

It is: 25

5-1 = 1/5 or 0.2

A^8 or A raised to the power of 8.

Negative exponents mean the reciprocal. 5^(-5) = 1/(5^5)=1/3125

I am going to say positive. If it is 5 -2 well that is 3, which is positive. Possibly you mean 5 with a small -2 slightly raised after it. That means 5 raised to the power of -2. Any time you have a negative exponent, you can take the reciprocal, and make it positve. So 5^-2 {the ^ symbol means to raise the power of} can be rewritten as 1/(5^2), which is 1/25. And this is a positive number as well.

Any number raised to the power 1 is that same number, x1 = x. For example, 51 = 5.

They are not! 5-3, for example is not 1/52 nor (1/5)2.

25 If you mean 5-1 the answer is .2 or 1/5

5^(-2) = 1/(5^2) = 1/25.

5 raised to the 3rd power is 125.

1 * 10-5 = 0.000001

negative 0.0016

1/125
