I face this problem too so I memorized some of the squares of the whole numbers. Such as 28²=784. But I suddenly found out that using calculator is better because......

Firstly, it is impossible to memorize sqrt of all the numbers. Numbers are infinite.

Secondly, There are fractions and decimals, I can't rely on my memory for that.

Thirdly, there are extremely big and extremely small numbers.

So after all, using calculator is the best.

You have to know at least 2 to 3 sides, as the guest has mentioned above.

Next, use the trig functions.

\({729}^{\frac{1}{6}}=\sqrt[6]{729}=3\)

\(\frac{log1}{1000}\)

= 0

\(log(\frac{1}{1000})\)

= -3

Yes. Definitely

First, calculate the slope(m)

\(m=\frac{y_2-y_1}{x_2-x_1}\)

Then the formula is y = mx+b

Substitute any pair of coordinates into x and y to calculate b

\(\frac{\pi}{ln(-1)}\)according to what i found secretly in my maths lesson

\(i\)according to what my maths teacher give me

\(\frac{log_ab}{log_ac}=log_cb\)

That's the formula.

True.

infinity is the biggest number already. If you add something to it, it will still be infinity. If you multipliy something to it, it will still be infinity. If you raise it to a power, it will still be infinity.

Rational.

9 - 3 ÷ 1/3 - 1

= 9 - 3 x 3 - 1

= 0 - 1

= -1
