Answer» Given (54)² But we can write 54 as 50+4 And also we know that (a + b)²= a²+2ab+b² By applying the above identity we get (54)²= (50+4)²= 50²+2(50) (4) +4² (50+4)²=2500+400+16=2916

Answer»

Given (54)²

But we can write 54 as 50+4

And also we know that (a + b)²= a²+2ab+b²

By applying the above identity we get

(54)²= (50+4)²= 50²+2(50) (4) +4²

(50+4)²=2500+400+16=2916
