What is the square of 93

Answer 1

Question :

→ What is the Square of 93 ?

Answer:

→ The square of 93 is 8649 .

Step-by-step explanation:

Given :-

→ The number whose square to be find = 93 .

To find :-

→ The square of 93 i.e., (93)² .

Solution :-

We have ,

= (93)² .

We can write this as :

= 93 × 93 .

= 8649 .

Now, verification :

We can write 93 as = ( 100 - 7 ) .

Now, using identity :

∵ ( a - b )² = a² - 2ab + b² .

⇒ ( 100 - 7 )² = (100)² - 2 × 100 × 7 + 7² .

⇒ (93)² = 10000 - 1400 + 49 .

⇒ (93)² = 10049 - 1400 .

∴ (93)² = 8549 .

Hence, it is solved .

Answer 2

To find the square of 93. We have to simply multiply it two times.

i.e.

=> 93 × 93

=> 8649

_____________________________

☆ VERIFICATION :

We can write 93 as

=> 93 = (100 - 7)

Now squaring on both sides

=> (93)² = (100 - 7)²

We know that

(a - b)² = a² + b² - 2ab

=> 8649 = (100)² + (7)² - 2(100)(7)

=> 8649 = 10000 + 49 - 1400

=> 8649 = 10049 - 1400

=> 8649 = 8649
