Bro at least write correctly

Help me you can solve this ( why 1/7=1 ? )

(1) 10%, 0.15, 16%, 7/10, 4/5 (2) 0.35, 3/8, 60%, 0.65, 2/3

1. 90 2. 6.25 3. 2.2 4. 13.5 5. 7.5

TYYYYYY😆😆😆😆😆 this helped me so much! TYYYYY🥰🥰🥰

I love your fast way. Thanks If 40% is 20 then 1% is 0.5 100% is 50❤🎉

I don't understand🤔🙄

Question 5. wrong values.

Thanks for helping me 😊

xy.yz/xz= 20.20/30 ; y² = 20/3 xy.xz/yz = 10.30/20 ; x² = 15 yz.xz/xy = 20.30/10 ; z² 60 x² + y² + z² = 245/3

Thanks you for helping us

Thanks you so much

asnwer=(b(2) isit 20. 50. 60

Thank you this helpss🎉🎉🎉🎉🎉🎉❤❤❤❤

asnwer=(2) isit 8.15.25 isit

Multiplying first two equations and dividing by last y^2 = 20/3 similarly x^2 = 15 and z^2 = 60 x^2+y^2+z^2 = 75+20/3 = 245/3

Nice

This is such a nice channel!

Love it. I am subscribing.

This is so cool and presented in a unique way!

Thank you❤❤❤❤❤❤

1. 50.

The pattern for 50s works with the 60s, except that 11 < n < 19. You will need those squares to do it, though.

😢

it's much easier and equally as fast to just learn to square the number rather than learning like 10 different tricks with no apparent pattern between them that each only work on a subset of the numbers and if you really want a formula that breaks down the numbers to make the calculations involved simpler, mn² (where m,n are digits 0-9) = 100m² + 20mn + n² works on all numbers 0-99

Nice but could you please write it more clearly❤

Useful trick.thank you

You need to teach yourself

Bhai mujhe redeem code send karo

Writing is very bad

handwriting shocking poor maths format

3/5

thanks!

your hand writing is not clear , the numbers could hardly be read

Next time make it clear. It's so hard to understand what you're writing😢

I don't understand the hand writing so i had to give up the video 😕

I have perfect score. But that not my formula I used.

Thank you🙏

Почему точки внизу, в этом положении они означают десятичные дроби В моем понимании целая часть 3^х, все остальное дробь Если имеется ввиду умножить то это другой знак (*)

noice one

If x == 1, then the LHS = 10, which is too low. If x ==2, then LHS = 68 which is too high. So there are no integer solutions, so ... next video !!!

X=3

9^m=3^-1,2m=-1,m=-1/2

My grandmother was complaining about the maths 😡

x has to be greater than or equal to zero, or there is no real solution. Now [√(x + 7) - √x] is always decreasing as x increases from zero to infinity. This being the case, √(x + 7) - √x = 1 has at most one real solution. Actually, where x = 0, then √(x + 7) - √x = √7 > 1, so we know there is exactly one real solution, because √(x + 7) - √x is always decreasing. By observation, we see x = 9 is a solution and it is the only solution and we are done.

X+(1/x)=2 is the same as x^2+2x+1=0 or (x+1)^2=0… ie x=-1… the result follows trivially

Way too much math for nothing. 8^X has to less than 520. Powers of 8: 1, 8, 64, 512 512 = 8^3, 520 - 512 = 8 = 2^3 Therefore X =3
