Marlinda :
how about ✓4225 = ? the answer is 65 but, if use metode 42 + 25 = 67 ?

Taegrr :
Neither an engineer nor a mathematician would use either of those methods.

The second method doesn't apply in all cases

Square root of 25 would be 7?

a normal person will always use 40x40 and 50x50 40²=1600 50²=2500 2025 is probably on 40s knowing that 5 is the last digit and only 5² had the last5 on it, its probably 45. it always works as long as it's a perfect square

GS Recover :
me: 2025 = 2000 +25 = 40x50 +25 = (45-5)(45+5) +25 = 45² -5² +25 =45² so sq(2025)=45

Mathematician: 2025 = 5 • 405 = 5^2 • 81 = 5^2 • 9^2 = 45^2 => √2025 = 45 Engineer: Calculator => √2025 = 45

nikitakucev56 :
глупый метод лучше использовать близлижайшие квадраты 40 и 50 1600 и 2500 если разница между ними и там и там одинаковая то корень равен среднему числу между ними а именно 45

BigBlueFreedom :
This is how my brain calculates the answer in 3 seconds, using deductive reasoning...50*50=too much, 40*40=too little. 2025 ends in 5, must be 45.

Don't hire that engineer.... he would make your building collapse... im pretty sure 😥

aarond0623 :
I noticed that 2025 = 25 * 81 (4 25s per 100, so 40 in 1000). So 5 * 9 = 45

The one on the right is a trick that only works in very specific cases.

مثلا لو قلت الجدر التربيعي للعدد 46 بيكون الناتج 2116 وبطريقتك نجمع 21 و16 يساوي 37 جدر 37 يساوي 1369
