Step-by-step explanation:

(-1+-1)+(-2+-2)+(-3+-3+-3)+(11+11)

2+4+(-27)+121

6-27+121

21+121

= 142

Answer 2

${\blue{\bold{ Question : }}}$

(-1)²+(-2)²+(-3)³+(11)²

$\underline{\green{\bold{ Solution : }}}$

(-1)² + (-2)² + (-3)³ + (11)²

= (-1 × -1 ) + (-2 × -2) + (-3× -3× -3) + ( 11 × 11 )

= 1 + 4 + (-27) + 121

= 5 - 27 + 121

= 126 - 27

= 99

$\boxed{\red{\bold{ Answer : 99 }}}$
