Question

Evaluate (-25)^3+(13)^3+(12)^3

Answer 1

Answer :

$( - 25 \times - 25 \times - 25) + (13 \times 13 \times 13) + (12 \times 12 \times 12) \\ = - 15625 + 2197 + 1728 \\ = - 11700$

Answer 2

Answer:

-11,700

Step-by-step explanation:

we know the formula

a^3+b^3+c^3-3abc=(a+b+c)(a^2+b^2+c^2-2ab-2bc-2ca)

if  a+b+c=0 then a^3+b^3+c^3 =3abc

since (-25+13+12)=0

(-25)^3+(13)^3+(12)^3 = 3(12)(13)(-25)

                                    = -11,700
