2½ ie 2 to the power of one-half. The power "one-half" applied to any value signifies that value's square root. Do not confuse with the power "-1" which indicates the reciprocal of the given value.
144-1/2 = 0.00347

One half to the negative first power is equal to the reciprocal of one half raised to the first power. The reciprocal of one half is two, so (1/2)^(-1) = 1 / (1/2) = 1 * 2 = 2.
Answer #1:Negative one-half to the negative 4th power, ie -((1/2)-4) equals -16Answer #2:Negative one-half to the negative 4th power, ie (-1/2)-4 equals +16
It is: 1/2 to the 11th power = 1/2048

31/2*91/3 = 3.602810866
It is: 2/3 times 1/2 = 1/3
5/2=2.5 2.5 to the power of 22 is 568434188.6
There are two square roots of i: (-1/square root 2)(1+i) and (1/square root 2)(1+i) so these are i to the one half power. Now to find -i to the one half power, multiply either of these by i, since i2 is -1. So (-i/square root 2)(1+i) and (i/square root 2)(1+i) are the square roots of -i. Verify this by direct multiplication.
Same as saying 2^5 = 32
