hmmm never mind u gave me a wrong formula A=p(1+r%)^n A=20000(1+5.5/100)^3 A=20000(1+0.055)^3 A=20000*(1.055)^3 now do what i told you recall that i=A-p

what could be the problem plug in those value A=20000(1+5.5/12)^3*12 A=20000(1+0.4583)^36 A=20000*(1.4583)^36 Puch ur calculator for (1.4583)^36 And multiply by 20000 and wuehi we are done!!!

wait do you mean to solve foy 3(2^y-1)=2^y+4 6^y-3=2^y+4 apply natural log log6^y-log3=log2^y+log4 log6^y-log2^y=log4+log3 ylog6-ylog2=log4+log3 y(log6-log2)=log4+log3 y=(log4+log3)/(log6-log2)....... not sure how you wanna keep on beaten these you can simplify from there

here u go as u=2^y.... plug in 3(u-1)=u+4 3u-3=u+4 3u-u=4+3 2u=7 u=7/2 now to solve for y apply natural log 2^y=7/2 log2^y=log(7/2) ylog2=log7-log2 y=log7-log2/log2=? or even y=log7/log4
