Answer:
→ 108 .
Step-by-step explanation:
Given:
→ a + b + c = 9 .
→ a² + b² + c² = 35 .
Now,
We know that,,
°•° ( a + b + c )² = a² + b² + c² + 2( ab + bc + ca ) .
==> 9² = 35 + 2( ab + bc + ca ) .
==> 81 - 35 = 2( ab + bc + ca ) .
==> ab + bc + ca = 46/2 .
•°• ab + bc + ca = 23 .
Again,,
We know that,
°•° a³ + b³ + c³ - 3abc = ( a + b + c )( a² + b² + c² - ( ab + bc + ca ) .
= ( 9 )( 35 - 23 ) .
= 9 × 12 .
= 108 .
Hence, it is solved.
