start at -25 and go up 20 units      It will be easiest to count in fives. :)

Yep, Max.....that is what it means....you got it!     Hydrogen peroxide is often used in rocket fuels and bombs as an oxygen source.

ECHO !

Thanks Chris,

I am not entirely comfortable with questions like this so it was really good for me to work through your answer :))

Thanks Alan :)

whats 4 small 8 time 4 indices

huh?????

\(4_8*4\)?????

-14 + 2x = 6

-14 +2x + 14 = 6 + 14

2x = 20

x = 10

\(-\frac{4}{5}\times \frac{9}{5}\\ =-\frac{4\times 9}{5\times5}\\ = -\frac{36}{25}\)

4/10 + 15/10 = (4+15)/10 = 19/10 = 1 9/10

\(\sqrt{-9}\)= 3i according to the calculator on this site, and it is correct.

2/3 = 66 2/3 % approximated as 0.67 or \(0.\overbrace{666666.....6}^{\infty}\)

\(H_2O_2\rightarrow H_2O+O_2\\ 2H_2O_2\rightarrow 2H_2O + O_2\)

Does that mean every 2 molecules of hydrogen peroxide will break down into 2 molucules of water and 1 molecule of oxygen gas?

Sorry for only knowing how to balance an equation LOL

30% x 3360

= 30/100 x 3360 <-- def. of percentages.

= 3/10 x 3360

= 3 x 336

= 1008

\(f'(c)=\dfrac{f(2)-f(0)}{2-0}=\dfrac{(2-2)^2-(0-2)^2}{2}=-2\\ f'(c) = 2c -4\\ \therefore 2c - 4 = -2\\ \begin{array}{rll}2c-4&=&-2\\2c &=&2\\c&=&1\end{array}\)

5x5 = 25.

I will do the assumption that you mean \(3.2\times 10^{-2} + 3.2\times 10^{-4}+2.8\times 10^{-2}\) because I see the pattern of scientific notation. (PS: I am learning scientific notation in school maths lessons too :) but actually not any teacher knows that I do self-learning for maths and I have already gone through this 3 years ago :P)

\(3.2\times 10^{-2} + 3.2\times 10^{-4}+2.8\times 10^{-2}\\ = ​​3.2\times 10^{-2} + 0.032\times 10^{-2}+2.8\times 10^{-2}\\ =(3.2 + 0.032 + 2.8)\times 10^{-2}\\ = 6.032 \times 10^{-2}\)

negative sign is identical to the minus sign.

Example: \(-5+1\)<-- in this case the '-' is the negative sign and the whole thing means 'negative 5 plus 1'.

Example 2: \(x - 5\) <-- according to some basic knowledge, this '-' is a minus sign and the whole thing means 'x minus 5'.

Just remember 1 thing. Minus signs cannot go in the very front while negative signs can. :)

young man??

More like a teenager :)

PS: I am 14 years old.

Hello :)

Welcome to the forum!!

Ooops.......   forgot to add in the 5's and 6's properly !     Thanx  Chris !  

2 h2 o2  =  2 h20 + o2   

   if you are trying to balance the equation for the breakdown of hydrogen peroxide to water and oxygen

3i     where 'i' is defined as the square root of (-1)        \(\sqrt{-1}\)

Rounded to the nearest WHOLE number, it is  2

Rounded to the nearest tenth it is   1.7

g'(x) = 2/3 x^(2/3-1) = 2/3 x^(-1/3) = 2/3  *  1/ (x^1/3)  =  2 / (3\(\sqrt[3]{x}\) )

if 'x' is ZERO it is undefined....or NOT ALLOWED  (You cannot divide by zero)

this means that the tangent line is a     hyperbolic or discontiguous   line    ?
