Generally, you understand the operations like addition, subtraction, multiplication, ...... etc., and then apply them in the word problems and daily life so that you can know, like, how much money have you used on food, how long time did you walk, or even how long did Mercury need to orbit around the Sun 5 times,...... there is just too much maths you can use in daily life problems.

If there is no maths, there will be no currency system and people just swap their properties like a sheep for 10 apples. Also because maths is used in science, if there is no maths, there will be no science.

Math is so much to learn.

Do you mean n^2 times n^3 or 2n*3n?

If yes,

n^2 * n^3 = n^5

2n*3n = 2*3*n*n = 6n^2

If no,

could you pls clarify this?

Do you mean \(y = {log}_{q}x?\)

If yes,

\(q^y = x\)

\(q = \sqrt[y]{x}\)

If no,

could you edit your question and state more clearly pls?

Do you mean x^2+4x+3 or x^2-4x+3?

x^2+4x+3 = (x+1)(x+3)

x^2-4x+3 = (x-1)(x-3)

l 2x + 6 l - 4 = -20

l 2x + 6 l + 16 = 0

2x + 22 = 0

x + 11 = 0

x = -11

Am i wrong?

LaTeX: Use the \over or \frac command

Calculator: just type a/b as a÷b

6. (16x^2y^-4z^-1)^0/y^2 = 1/y^2

8. Anything to the power of 0 is 1

Therefore equals to 1

10. \({{a}^{{2b}^{3}}}^{-1}= \frac{1}{{{a}^{{2b}^{3}}}}\)

Btw the question numbers i mentioned are Pythagorean triples xD

Hello Guest!

it is acually 19 my good sir

(((115200*x4)*x5)*x7)*x9+1076

(((7000000000/46%)/.17%)/5.52%)

= (((7000000000÷0.46)÷0.0017)÷0.0552)

= 7000000000÷0.46÷0.0017÷0.0552

= 162163163942325.5124355980573316286232

The answer is 145,153,076

sin takes values between 1 and -1, so there is no angle whose sin is 83/28

Pressure head = p/(rho*g)

Use the following:

p_B + (1/2)*rho*v_B^2 = p_A + (1/2)*rho*v_A^2                   p_B = rho*g*h

v_A*Area_A =  v_B*Area_B

p_B + (1/2)*rho*v_B^2  =  p_C + (1/2)*rho*v_C^2  + (0.15/2)*rho*v_B^2

.

v_C*Area_C = v_B*Area_B

Volume flow rate = v*Area

v is velocity,  p is static pressure

.

sin=2324

It wasn't about the wrong notation it was more like seeing a y as function for the first time. I was so confused I literally focused on that question for 30 mins to no avail. Ended up losing more marks due to not answer a majority of easier questions. I need better testing habits. Anyways good night, the butts known as our district decided to throw us a suprise State Standards Test. Oh boy.

Come on High School Calc,

If you only put the wrong symbol out the front then you are not going to lose much marks - maybe not any...

Thanks Melody! I really appreciate the clarification. Now if you'll excuse me, I'm going to go cry myself to sleep.

Yes it is pretty much the same thing.  Only the notation is really different. 

eg

\(f(x)=5x^2+6x+7\\ f'(x)=10x+6\\~\\ wheras\;if\\ y=5x^2+6x+7\\ then\\ \frac{dy}{dx}=10x+6\\ or\\ y'=10x+6\\ \)
