- (a+b)²= a²+2ab+b²
- (a+b)²= (a-b)²+4ab

⭕🚩The speed of the boat is 10 km per hour in favor of the current. and 2 km upstream. What is the velocity of the current?

Technique-

Velocity of current = (Velocity of boat upstream – Velocity of boat upstream) /2

= (10 – 2)/2=

= 4 km.

🚩A boat moves 8 km/hr upstream and 4 km/hr upstream.

goes What is the speed of the boat?

★ Technique-

Velocity of boat = (Velocity of boat upstream + Velocity of boat upstream)/2

= (8 + 4)/2

=6 km.

🚩 Speed of boat and current is 10 km/h respectively. and 5 km. 45 km by river. How long will it take to come back once the way?

technique-

★Total Time = [(Total Distance / Speed Up) + (Total Distance / Speed Up)]

Answer: Speed of boat in favor of current = (10+5) = 15 kmph.

Speed of boat upstream = (10-5) = 5km/h

[(45/15) +(45/5)]

= 3+9

= 12 hours

⭕🗣️👉Let’s make it easy

Topic: Finding square root in 10 seconds.

Note: Numbers whose square root is between 1 and 99 can be easily calculated by this method. Questions must contain whole numbers. That is, if the answer is a decimal fraction, then this method will not work.

Must read carefully and practice. Or forget it.

But let’s get started. First memorize the squares of numbers 1 to 9. Hope everyone knows them. For convenience I am writing below-

1 square = 1, 2 square = 4

3 square = 9, 4 square = 16

5 squared = 25, 6 squared = 36

7 square = 49, 8 square = 64

9 squared = 81

If you look at each square number here, you will see that in the case of the last digit –

The square of 1 and 9 has the same last digit (1, 81).

The square of 2 and 8 has the same last digit (4, 64).

★ The square of 3 and 7 has the same last digit (9, 49);

★ The square of 4 and 6 has the same last digit (16, 36);

and 5 alone frown emoticon

If there is any problem to understand till Eddur then read again.

🗣️Example:- Find the square root of 576.

👉First step: Look at the unit’s digit of the number whose square root is to be determined. In this case it is ‘6’.

👉 Second step: From the list above, take the last number 6 of the square of that number. 4 and 6 in this case. Again, note that the squares of 4 and 6 are 16 and 36 respectively; Whose unit cell digit is ‘6’. Got it? If you don’t understand, read it again.

👉 Third step: Write 4 / 6 in the notebook. (We’ve got the unit’s digit of the answer, which is either 4 or 6; but which one? You’ll get the answer in step eight, read on…)

👉 Fourth step: Look at the rest of the numbers after excluding the units and decimals of the question. In this case it is 5.

Step 5: Take the square root of the number closest to 5 from the above list. In this case 4, which is the square of 2. (We get the decimal place digit of the answer, which is 2 )

👉Sixth step: Multiply the next number with 2. That is 2*3=6

👉Seventh step: See if the number (5) obtained in the fourth step is smaller or larger than the number (6) obtained in the sixth step. If it is small, I will take the smaller number found in the third step, if it is larger, I will take the larger one. (Got it? Or read again)

Step 8: In our example 5 is the smaller of 6, so we will take the smaller number of 4 / 6 i.e. 4.

👉Ninth step: I remember, in the fifth step I got the number of tens place 2 now I got the number of units place 4. So the answer will be 24

Feeling difficult? Not at all, try some practice. I don’t think it will take long.

🗣️Example:- Find the square root of 4225.

Remember 5 that was alone? But since he is alone, your job is much easier. See why since the last digit of the question is 5, the unit cell digit of the answer must be 5.

– If the unit and decimal places of the question are removed, the remainder is 42.

– The nearest whole square number to 42 is 36, whose square root is 6. So the answer is 65
