Now space 500 minus 343 equals 157 space and space 512 minus 500 equals 12 As space 500 space is space nearer space to space 512 space approximately comma space the space value space of space cube root of 500 space is space 8. left parenthesis ii right parenthesis space 15 cubed equals 3375 space and space 16 cubed equals 4096 As space 4000 space lies space between space 3375 space and space 4096 comma space its space cube space root space wil space lie space between space cube root of 3375 space and space cube root of 4096 that space is comma space between space 15 space and space 16. Now space 4000 minus 3375 equals 625 space and space 4096 minus 4000 equals 96 So comma space the space approximate space value space of space cube root of 4000 space is space 16. end style
