(1+x/100)^3 = 4 (1+x/100) = 4^1/3 (4 to the power 1/3) x/100 = 4^1/3 - 1 x/100 = 0.58740105... (by calculator) x = 58.740105...

其他解答:

(1+x%)^3=4 (1+x/100)^3=4 [(100+x)/100]^3=4 (100+x)^3/1000000=4 1000000+x^3=4000000 x^3=3000000 x=144.224957 144.224957．100% =1.44224957% HOPE THIS CAN HELP YOU LA CAN YOU PLEASE CHOOSE ME AS THE BEST ANS.... ( T ^ T )|||||(1+x%)^3=4 1^3+x%^3=4 x%^3=3 x%=1.44224957 x=0.0144%(corr to 3sig. fig.)
