How do you find out 2 to the negative 1 power?
If it is to a (-) power then that is the same as saying it is 1 divided by 2 to the power of 1. 2 to the power of 1 is 2, and so 1 divided by 2 is 1/2 or 0.5.
How do you expand a negative power For example 2 to the 2nd power is 2x2 how do you expand 2 to the power of -1?
for expanding negative powers of a number you take 1 divided by the number to the positive power and expand. For example 2 to the -1 power is 1 divided by 2 to the + 1 power = 1/2 2 to the -3 power is 1 divided by 2 tot he + 3 power = 1/8 this is called inverse
What is -2 to the 1st power?
-2 to the first power = -2^1. -2^1 = -2*1. -2*1 = -2. The answer is negative two.
What the value of 2 to the power of 1?
Just 2 2 to power 3 is 2x2x2=8 2 to power 2 is 2x2=4 2 to power 1 is 2
If power of x is 2 divided with power of x 2?
1

How do you work out 2 to the power of minus 2?
For anything to the power of a negative, put the number as the denominator in 1/? and then solve (ex: 2 to the power of neg. 2 = 1/2 to the power of 2 = 1/4)
Is -2 to the power of -3 the same as -2 x -2 x -2?
sorry if this is worded weirdly, im 11 so... -2 to the power of 3 is -2 x -2 x -2 anything to the 0th power is 1 then it becomes a fraction so like 2 to the -2 power is 1/2 to the 2nd power so 2 to the -3rd is 1/2 to the 3rd so 1/8 * * * * * A negative power is a reciprocal of the positive power. So (-2)-3 = 1/((-2)3 = 1/[(-2)*(-2)*(-2)] =1/(-8) = -1/8
What must you turn a negative exponent problem into?
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.
How are 2 to the 1 power and 2 to the -1 power related?
They are mutual reciprocals.
How much is 2 to the power -2?
2 to the power of -2 is equal to 1/4.x to the power of -y is equal to 1/xy.
What is a single power in maths?
A number to the power 1 is that number. For instance 2 to the power 1 (written here as 2^1) is 2. 2^0=1 2^1=2 2^2=4 2^3=8 2^4=16
What is 3 to the power of 1 multiplied by 3 to the power of minus 2?
3 to the power of 1 is 3. 3 to the power of minus 2 is equal to 1 over 3 to the power of 2. 3 to the power of 2 is 9. 3 to the power of 1 times 3 to the power of minus 2 is the same as... 3 divided by 3 to the power of 2. So that gives us 3 divided by 9 which is the same as 1/3.
What is -1 by the power of 3?
- 1 to the power 2 = 1 and to the power 3 takes you back to -1.
