Answer 2

Answer:

Let us simplify the expression, we get

(52)3 = (50 + 2)3

(50 + 2)3 = (50)3 + [3 × (50)2 × (2)] + [ 3 × (50) × (2)2] + (2)3

By using the formula,

(a + b)3 = a3 + 3a2b + 3ab2 + b3

Here a = 50, b = 2

Now, substitute the value we get

= 125000 + (3 × 2500 × 2) + (3 × 50 × 4) + 8

= 125000 + 15000 + 600 + 8

= 140608

∴ (52)3 = (50 + 2)3 = 140608
