55 = 3125 5 x 5 x 5 x 5 x 5 = 3125 The answer can be obtained via a calculator or by the use of logarithms.
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.
No, to be linear, both the power of x and y need to be 1. Since x is squared, the power of x is 2.
X=5
