When a number is raised to a negative exponent, it means the reciprocal of that number raised to the positive exponent. Therefore, 5 to the power of -1 is equal to 1/5, or 0.2. This is because any number raised to the power of -1 is the multiplicative inverse of that number, which is the reciprocal.

What is a number raised to the negative power?
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.)
What is 10 to the power of negative 5?
0.00001 or 1 over 100,000
