Consider the function ln(1+9x). write a partial sum for the power series which represents this function consisting of the first 5 nonzero terms. for example, if the series were ∑∞n=03nx2n, you would write 1+3x2+32x4+33x6+34x8. also indicate the radius of convergence. partial sum: equation editorequation editor radius of convergence

because 1.2 isnt half of 6 duh

since your problem is x^4 = 81, what you have to undeo is the "to the fourth power" part.

the inverse (opposite operation) of "to the fourth power" is "to the fourth root".

  (x^4) ^ ¼   = 81 ^ ¼  

  81 = 3^4     so (3 ^ 4) ^ ¼   =   3 ^ 1   = 3

by hand: (3 ^ 4) ^ ¼   =   3 ^ (4 x ¼) = 3 ^ 1   = 3   (when you take a power to a power, multiply the exponents.)

or, do it by calculator. one way of finding the fourth root is to use ^ (1/4)

72 is the answer to this problem
