Answer 1

HELLO.....FRIEND!!

THE ANSWER IS HERE,

$= > \: ({ - 12})^{3} + ({7})^{3} + ({5})^{3}$

This is in the form of

$= > \: {a}^{3} + {b}^{3} + {c}^{3}$

So, Lets find a+b+c

=> -12+7+5

=> 0.

Here, a+b+c=0. So,

$= > \: {a}^{3} + {b}^{3} + {c}^{3} = 3abc$

=> 3 (-12)(7)(5).

=> -1260.

2)

$= > ( {28})^{3} + ( { - 15)}^{3} + ( { - 13})^{3}$

This is also in the form of

${a}^{3} + {b}^{3} + {c}^{3}$

So, Lets find a+b+c

=> 28-15-13

=> 0.

Here, a+b+c=0.So,

$= > {a}^{3} + {b}^{3} + {c}^{3} = 3abc$

=> 3 (28)(-15)(-13)

=> 16,380.

:-)Hope it helps u.
