\(A=(z+7)^3?\\A=(z+7)^3\\\sqrt[3]{A}=z+7\\z=\sqrt[3]{A}-7 \)

I am now 14 years old so that statement is true. Thx everyone :D

(PS: I have not been online at the forum for like 5 days so I didn't reply.)

\((22-w)/3=-7\\ 22-w = -21\\ w = 43\)

We usually use calculators. But I don't like that way. I want exact values some times.

Example: \(\sqrt{88}\\ = \sqrt{4}\sqrt{22}\text{<}--\boxed{\sqrt{ab}=\sqrt{a}\cdot \sqrt b}\\ = 2\sqrt{22}\)

There I got the exact value of sqrt 88.

9+11 =20

Gonna explain why I have used '10 thousand years' above.

Western numbers units = thousands, millions, billions, trillions, so on.....

Chinese(bc i am chinese) numbers units = 10 thousands, 100 millions, so on.

Btw bye Santos. :D

Limits for this equality is:

1) y must be a positive integer.

2) x must be integer or the mod function wouldn't work.

3) If x is less than 0, x need not be larger than y and the equality works.(If you know how to do mod functions with negative numbers. Example: -2 mod 7 = 5)

4) \(\lfloor x\rfloor\) means the nearest integer smaller than x.

Also an Admin whose username is admin is a user(an admin?) who stayed soo long on this forum. I think admin and asinus are one(two?) of your buds too

Gonna answer your question although it's already 13 hours ago XD.

\(6\frac{45}{150}\\ = 6\frac{45\div 15}{150 \div 15}\\ =6\frac{3}{10}\text{ OR 6.3}\\ \text{Same answer as Math=Emojicool}\)

\(\dfrac{70}{25}\\ = \dfrac{50+20}{25}\\ = \dfrac{50}{25}+\dfrac{20}{25}\\ = 2 + \dfrac{4}{5}\\ = 2\dfrac{4}{5}\\ = 2.8\)

Or you just divide it by calc.
