Answer 2

same concept as the last one we did


2^n = 7/8, logging it out we get n=log(7/8)/log(2)

so n* 5568

Answer 3

got a little something off there

Answer 4

1/2^n = 7/8

2^n = 8/7

Answer 5

n = log(8/7)/log(2) :)

Answer 6

1073 yrs

Answer 7

thanks!!

Answer 8

all that does is change the sign in the end ... but its good to be 'conventional'

Answer 9

yep, 1072.64...
