Answer 1

Answer:

Step-by-step explanation:

(103)³

=(100+3)³

=(100)³+3(100)²(3)+3(100)(3)²+(3)³

=1000000+90000+2700+27

=1092727

Answer 2

Answer:

(103)³ = 1092727

Step-by-step explanation:

(103)³

= (100+3)³

= 100³+3×100²×3+3×100×3²+3³

/* By algebraic identity:

(a+b)³ = a³+3a²b+3ab²+b³*/

= 1000000+90000+2700+27

= 1092727

Therefore,

(103)³ = 1092727
