Question

you have any questions in maths about finding the square of a number ???​

Answer 1

Answer:

Step-by-step explanation:

We can write the square of 46 as follows by expanding it the number as a sum of 40 and 6:

(46)2=(40+6)2

⇒(46)2=[4(10)+6]2

We know that according to the identity: (a+b)2=a2+b2+2ab , therefore:

⇒(46)2=[4(10)]2+[6]2+2(4)(6)(10)

⇒(46)2=42×102+62+2×4×6×10

⇒(46)2=(16×100)+36+480

⇒(46)2=1600+480+36

⇒(46)2=2116
