Say how much the full square number two will be

With full class number:

Today our main issue is the full class number. But before that let’s learn the strategy of solving two interesting questions in mathematics. It is a matter of fact to apply mathematical calculations based on logic. If we say (55 × 55) = 100, (66 × 66) = 144, (77 × 77) = 196, (88 × 88) = 256, then (99 × 99) =?

First of all, I think it’s a fabulous problem. Actually (55 × 55) = 3025, 100 can never be 100 But in the form of a rhythm it is written as That’s why I said first, ‘if … is’

Now let’s say, if the first equations are considered correct, then what will be the last product? To answer this, we first saw some of the series in the given series and found out the inner matches. There is a similarity between each amount. It turns out, the first digits of each letter are two digits and the same digit is written twice. The square number of these two sum sum is shown as the square of the whole number. For example: (55 × 55) = (5 + 5) 2 = (10) 2 = 100 Now we can find out the answers to the main problem. (99 × 99) = (9 + 9) 2 = (18) 2 = 324

See another interesting account. (11/5) + (12/5) + (13/5) + (14/5) + (15/5) =? What is the easy way to find out the sum of this section? For the answer we will first see, from 11 to 15, five of the five numbers in the series have been added by dividing 5. So we can write this series (11 + 12 + 13 + 14 + 15) / 5 = {(11 +15) × 5/2} / 5 = {(26 × 5) / 2} / 5 = (130/2 ) / 5 = (65/5) = 13.

A common solution: You can sit four around a table. To accommodate 30 friends, another table was arranged for a table to sit in a tall table. Now say how many tables do you need?

Answer: 14 tables are needed. Of course if you consider yourself to be more than 30 friends, then 15 tables will be required.

Many enthusiastic readers answered. Many answers came in my e-mail address. The answer to almost all of them is correct. Thank you all.

How did you answer?
First, I calculated, six people sitting on the two sides of the table. Remaining (30 – 6) = 24 people The two sides of the middle table can sit on the two sides. So for the remaining 24 people need 12 tables. So the total number of tables (2 + 12) = 14 To find out this answer, we can find out the number of tables for a number of friends using a formula. (Number of Total Tables – 2) = (Number of friends – 6) / 2 Or, (number of friends – 6) / 2 with the number obtained from the calculation, then the number of tables can be found. In our case, the number of tables = {(30 – 6) / 2} + 2 = (12 + 2) = 14
