Question

(128)^2-(72)^2 solve this?

Answer 1

Hello!
Here is your answer

$(128) {}^{2} - (72) {}^{2}$
this is in the form
$x { }^{2} - y {}^{2} = (x + y)(x - y)$
so the answer is

$(128 + 72)(128 - 72)$
$= 200 \times 56$
$= 11200$

Answer 2

The value of (128)²-(72)² is 11200.

Given:

(128)²-(72)²

To Find:

We are required to solve the given term.

Solution:

The given term ((128)²-(72)²) is in the form of a²-b².

The formula of a²-b² is

a²-b² = (a+b)(a-n)   -------(1)

a = 128, b = 72

On substituting the values of a and b in equation(1) we get

(128)²-(72)² = (128+72)(128-72)

(128)²-(72)² = 200×56

(128)²-(72)² = 11200

Therefore, The value of (128)²-(72)² is 11200.
