....,........

Answer 1

Welcome to the concept of squares!

Square means multiplying a number by itself twice.
Ex:- 3²=3×3=9

So, 8²=8×8=64

Answer 2

Answer:

Value of  8² = 64.

Step-by-step explanation:

Square of numbers:

• A "Square Number" is the product of multiplying an integer or number (not a fraction) by itself. For instance, 3 x 3 = 3², or 3 multiplied by 3 becomes 3 squared. In essence, a square number is the result of multiplying an integer or number by itself exponentially.
• Additionally, if we multiply the number once more by itself, we obtain the integer's cube: a x a x a = a³.
• Square numbers are always positive. If negative sign is multiplied by itself, it results in positive sign (+).
• For example, (-4)² = 16.    

Properties of Square numbers:  

• Never should a number that has a 2, 3, 7, or 8 at the unit's position be a perfect square. Thus, none of the square numbers can finish in 2, 3, or 7 or 8.
• A number is a perfect square number if the number of zeros at the end is even. If not, we can state that no number with an odd number of zeros can ever be a perfect square.
• Even numbers always result from squared even numbers. In addition, squared odd integers always result in odd numbers.
• If a natural number other than one is squared, it must be either a multiple of 3 or a multiple of 3 that is greater by 1.  
• The square of a natural integer that is not one should either be a multiple of four or exceed a multiple of four by one.

               The value of 8² = 64
