a3*a-2 = a(3-2) = a
That is the definition of negative powers.
(-2)(2^3) = (-2)(8) = (-16)
6 to the negative 2nd means that it equals 1 over 6 to the negative 2nd.
it is a positive fraction 5^-2=1 over 5^2 answer is 1 over 25
a3*a-2 = a(3-2) = a
That is the definition of negative powers.
It is always negative when raised to an odd power and always positive when raised to an even power -2 to the third power = -2 x -2 x -2 = -8 -2 to the fourth power = -2 x -2 x -2 x -2 = +16
(-2)(2^3) = (-2)(8) = (-16)
6 to the negative 2nd means that it equals 1 over 6 to the negative 2nd.
it is a positive fraction 5^-2=1 over 5^2 answer is 1 over 25

2-3 in standard notation is 0.125
(2)-1/3 x (4)-1/3 = (2 x 4)-1/3 = (8)-1/3 = 1/81/3 = 1/2
Oh, what a happy little question! When you have 2 to the power of -6, it means you're taking the reciprocal of 2 to the power of 6. So, 2 to the negative 6th power is 1 over 2 to the 6th power, which simplifies to 1 over 64. Just a little fraction painting to brighten your day!
