Given 46^3 + 34^3
= > (40 + 6)^3 + (30 + 4)^3.
= > 40^3 + 6^3 + 3 * 40 * 6(40 + 6) + 30^3 + 4^3 + 3 * 30 * 4(30 + 4)
= > 64000 + 216 + 720(46) + 27000 + 64 + 12240
= > 64000 + 216 + 33120 + 27000 + 64 + 12240
= > 136640.
Hope this helps!

Answer :
Now,
46^3 + 34^3
= (46 + 34) (46^2 - 46 × 34 + 34^2)
= 80 × (2116 - 1564 + 1156)
= 80 × 1708
= 136640
Identity Rule :
a^3 + b^3
= (a + b) (a^2 - ab + b^2)

Now,
46^3 + 34^3
= (46 + 34) (46^2 - 46 × 34 + 34^2)
= 80 × (2116 - 1564 + 1156)
= 80 × 1708
= 136640
Identity Rule :
a^3 + b^3
= (a + b) (a^2 - ab + b^2)
