angy 5,950 Posted November 18, 2016 Share Posted November 18, 2016 The answer is apparently x=5, but how do you solve this? 14^(x+2) / 7^x = 6272 Hope you understand, it's hard to write equations here Link to comment Share on other sites More sharing options...

pr0chicken007 2,091 Posted November 18, 2016 Share Posted November 18, 2016 14^(x+2) / 7^x = 6272 14^x*14^2/7^x = 6272 ---> 2^x = 6272/196 --->2^x = 32 ---> x=5 Link to comment Share on other sites More sharing options...
