I am not entirely sure what you mean: If you raise something to a power, you automatically have an exponent.(-5) to the power (-1) is the reciprocal of (-5) to the power 1, so you have 1 / (-5), or -1/5.
If you mean 5 to the power of -1 then it is 1/5
It is: 5/5 to the power of 5 = 1 or 5 to the power of 5-5 = 1
It is equivalent to 1 over 5 to the power of 5, or 1 over 3125.
10 to the 0 power is 10 and 5 to the 0 power is 5 so 10 multiplied by 5 equals 50.
It is: 1/8 to the power of 5 = 1/32768
Any number to the power of one equals the original number. 5 to the power of 1 is 5.
They are not! 5-3, for example is not 1/52 nor (1/5)2.
1/(1^5)= 0.00001
