What is one half to the negative first power?
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.
2 to the negative first power?
A negative power/index/exponent simply inverts the expression and the power now becomes a positive number. 2-1 = 1/21 = 1/2 = 0.5 Note : This also applies if the term is the denominator. For example : 1/3-2 = 32 = 9.
2 to the negative 1 power?
2-1 = 1/(21) = 1/2 = 0.5
If x to the power 4 plus 1 upon x to the power 4 equals 47 then what will be x to the power 3 plus 1 upon x to the power 3 equals what?
A similar question can be solved as below : If x to the power 4 plus 1 upon x to the power 4 equals 23 then what will be (x minus 1 upon x) to the power 2 equals what?a2 + b2 = (a + b)^2 - 2ab.so (x^2 )^2 + (1/x2)^2 = (x^2 + 1/x^2)^2 - 2 = 23.so (x^2 + 1/x^2) = 5.therefore(x - 1/x)^2 = (x^2 + 1/x^2) -2 = 5 -2 = 3.
What is 4 to the 2nd power?
-2

What is the derivative for 3x to the power of -1?
4
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 can you rewrite the number 1 as 2 to a power?
2 to the zero power = 1
How are 2 to the 1 power and 2 to the -1 power related?
They are mutual reciprocals.
The numerical value of 2 to the power of 1?
2^(1) = 2 Remember this table of powers. n^(0) = 1 n^(1) = n n^(2) = n^(2) e.g. 2^(0) = 1 2^(1) = 2 2^(2) = 4 et seq., NB When the index number of '1' is used , it is only there as a guide to manipulating indices ( index numbers).
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 2 to the first power?
2.
