4^(-3) = 1/4^3 or 1/64
Yes
To raise something by the power of negative one, take the reciprocal of the number. In this instance, -3/4-1 = -4/3 or negative four thirds. Expressed as a decimal, this is equal to -1.3 recurring (that is, -1.3333...)
16
16 -2-4 = 0.0625
1/4 or 0.25 or 4-1
(40x^6-24x^4)/8x
-3/4 divided by -1/4 = 3
No Actually... x^(-y) is equal to 1/x^y. 2^(-2) is equal to 1/2^2 which is equal to 1/4 or 0.25.
(-3)4 = 81 (positive).
Well, honey, any quotient equal to 4 to the negative fifth power is just 1 over 4 to the fifth power, which simplifies to 1 over 1024. So, grab your calculator and divide 1 by 1024, and you'll have your answer faster than you can say "Golden Girls marathon."
8 and 3/4
yes ma'am ADDED: The above is wrong. 2^-2 means 1/2^2 or 1/4 -2^2 can equal - 4
