Help, I can't figure out how to solve this problem. 10 years ago, a lender provided a $2-million loan for the financing of an apartment building. The loan required annual payments and was fully amortizable over 10 years at an annual interest rate of 9%. It also came with five discount points. The loan has been paid off (in 10 years). What is the lender's yield for this loan?

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)

step-by-step explanation:

is should be y = 5x

step-by-step explanation:

correct me if im wrong

y + 11 = (1/4)(x + 16)

what level of math? also i don't need to be paid if i can you.
