@mathexpert30: which method you prefer ? #math #mathematics #StudyTips #unitedstates #usa🇺🇸

Taegrr :

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

bcc limmm :

if the engineer method doesn't work all the time isn't it just coincidence and shouldn't count as a method?

GS Recover :

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

اعوان زادہ⚜️☣️ :

1st method is true second is false

ابو يوسف :

what about 1936,try

Nobody :

wth are these sheet methods

Clarissa NM :

Where to choose the number 3 from? 🗿

Farhan :

you forgot to put postive and negative signs along with your answer.

tony.b :

Poi dice che cascano i ponti....

ꮪάզ𝘭άꜞ𐌽 Baloch :

144 please

aarond0623 :

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

Alain_Derouin :

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

Szczurek9999 :

2026 =46 46*46 =2116

Explore Next (Saqib Asam) :

Is it applied on all cases?

Bestemmiolino Sassaroli :

of course: try with 2116 ...

wuiles1972 :

what a nonsense

Muhammad Farhan :

use calculator 😂😂

Zenitsu :

what about 6241 85? hahaha ayaw ko na mag engineer

Rosa Luna :

el ingeniero usa calculadora

ITalkToMyFridge :

So sqr(3045) = 75 ??? Total BS…

DJ :

Ends in 5, divide by 5. 5*405, ends in 5, divide by 5 again. 81. Recognize 9*9=81, therefore (5*9)^2 is 2025

TJL :

ngacapruk , kebetulan aja itu, cara keduanya bisa gitu

purpleblossom :

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