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.
2 to the 7th power equals 128....
-1 to the 7th power equals -1
logx^2=2 2logx=2 logx=1 10^1=x x=10
A negative power equals the reciprocal of the same number to the equivalent positive power. Example : 2 ⁻³ = 1/2³ Then 8⁻² = 1/8² = 1/64 = 0.015625
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).

Any number to the power of 0 equals 1.Therefore 2 to the power of 0 = 1
2^0=1 anything^0=1
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.
8 1/3 = ab^-1, 1.8 =ab^2
1 + 2 + 4 + ... + 2n = 2n+1 - 1
rearrange the following: A^(1/n)= the nth root of A. eg A to the power 1/2 equals the square root of A. A to the power 1/3 equals the cube root of A. etc.
Any number raised to the power of zero equals 1. For example, start out with 2^3 = 8. Then divide by 2 and get 2^2=4. Divide by 2 again: 2^1=2. Divide by two again: 2^0=1.
Since 2^2=4 ........1 and 2*0=0 ..........2 Dividing both sides of equation 1 by 2^2 2^2/2^2=4/2^2 => 2^(2-2)=4/4 or 2^0=1 (QED)
