Negative exponents mean reciprocals. Look at this pattern: 10^3 = 1000 10^2 = 100 = 1000/10 10^1 = 10 = 100/10 10^0 = 1 = 10/10 10^-1 = 1/10 10^-2 = 1/100 etc Other examples: (2/3) ^ -1 = 3/2 (1/10) ^ -1 = 10 3 ^ -2 = 1/9

10 ^-1 = 1/10^! Because ethe opposite of multiplication is division. They are both equal. One expressed in multiplication , and one expressed in division form 2x3= 6 6/3=2 http://www.mathsisfun.com/algebra/negative-exponents.html

1 is the zero power of ten. So its likely that it will equate to one tenth of ten when subtracted.

Because negative exponent means you reciprocate it. For instance: 7^-2=1/49 3^-3=1/27 10^-2=1/100 x^-1=1/x Hopefully, that helps you. Hooah!
Positive: 50 %

By definition. Also by definition 5^2 = 5 x 5 So 5^-1 = 1/5^1
Positive: 37.5 %
