(100+7)^2

by using identity a^2+b^2+2ab

let 100 as a and 7 as b

=(100)^2 +(7)^2+ (2)(100)(7)

=10000+49+1400

=11449

mark me as brainliest

Answer:

Given :

(107) ^{2}

So we get,

(107) ^{2} (100 + 7) ^{2}

According to the equation

(a−b) ^{2}  =a ^{2}  −2ab+b ^{2}

Using the formula we can it write it as

(107) ^{2}  =(100) ^{2}  +2(100)(7)+(7) ^{2}

On further calculation we get,

</p><p>(107) ^{2} =10000+1400+49 </p><p>(107) ^{2} </p><p> =11449
