Question

Use the square of a binomial to find the value of 512.

Hint:

The methods used to find the product of binomials are called special products.
Multiplying a number by itself is often called squaring.
For example (x + 3)(x + 3) = (x + 3)2

The correct answer is: 2601


    512 can be written as  (50 + 1)2 which can be further written as (50 + 1)(50 + 1)
    (50 + 1)(50 + 1) = 50(50 + 1) + 1(50 + 1)

    =  50(50) +  50(1) + 1(50) + 1(1)

    = 2500 + 50 + 50 + 1

    = 2500 + 100 + 1

    = 2601
    Final Answer:
    Hence, the value of 512 is 2601.
