Question

if acube+bcube=343anda+b=7find the value ofasquare-ab+bsquare​

Answer 1

Answer:

( a² - ab + b² ) = 49

Step-by-step explanation:

Given:

a³ + b³ = 343

a + b = 7

Find:

a³ + b³  = ( a +b ) ( a² - ab + b² )

By Substituting the values,

343 = 7 ( a² - ab + b² )

343/7 = ( a² - ab + b² )

49 = ( a² - ab + b² )

∴ ( a² - ab + b² ) = 49
