The value of 3 to the negative power of 2 is 1/9.

Just 2 2 to power 3 is 2x2x2=8 2 to power 2 is 2x2=4 2 to power 1 is 2

1/2, or .5When you raise a number to a negative power, you are dividing one by that number to the positive version of that power. For example, 5^-6 = 1/(5^6).So, 2^-1 = 1/(2^1), or 1/2, which = .5

The value of 4 to the power of -2 is 0.0625

1. Anything to the power of 0 is equal to 1.

A negative exponent is 1 over the base to the power of the absolute value of the exponent. For example 2 to the power of -1 is 1/2, 2 to the power of -2 is 1/4, or (1/2) squared, and 2 to the power of -3 is 1/8, or (1/2) cubed.

1/4

2^-6 = 1/(2^6) = 1/64 = 0.015625

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.

Any number to the power of zero is by definition 1(one)

find the derivative of y=x(1-x to the power 2 ) square/(1+xto the power2)half first take the natural logarithms of the absolute values of both sides ln, the absolute value of y=ln the absolute value of x(1-x to the power2) to the power two/(1+x to the power two) to the power half=... . then take the derivatives of both sides 1/y y`=1/x+2/1-x to the power two (-2x)-1/2... .

It is the exponential series of 2, or 2n but offset by one value.

It can be a negative or a positive number depending on the absolute value of the power.e.g.(-4) to the power of -2 gives (1/16) and(-4) to the power of -1 gives (-1/4)

1 to the power of anything is always 1.
