Question

46 ka cube + 34 ka cube using identities step by step explanation​

Answer 1

Given: The term 46³ + 34³

To find: The value using identities.

Solution:

• Now we know the identity:

                a³ + b³ = (a + b)(a² - ab + b²)

• So applying this in the given expression, we get:

                46³ + 34³ = (46 + 34)(46² - 46x34 + 34²)

                                 = (80)(2116 - 1564 + 1156)

                                 = (80)(1708)

                               = 136640

Answer:

             So the value of 46³ + 34³ is 136640.
