It looks like you made up this one yourself, with several mistakes in writing it down!!.

log((log(2 sin(3 cos(4 tan(sqrt(5))))))/(log(10)))

=-1.3579322.......etc.

It"s simple you type a letter (or letters) that does not have another meaning like pi or e.

Simplify the following:
2/sqrt(12)-sqrt(8)

sqrt(12) = sqrt(2^2×3) = 2 sqrt(3):
2/2 sqrt(3)-sqrt(8)

2/(2 sqrt(3)) = 2/2×1/sqrt(3) = 1/sqrt(3):
1/sqrt(3)-sqrt(8)

sqrt(8) = sqrt(2^3) = 2 sqrt(2):
1/sqrt(3)-2 sqrt(2)

Rationalize the denominator. 1/sqrt(3) = 1/sqrt(3)×(sqrt(3))/(sqrt(3)) = (sqrt(3))/(3):
(sqrt(3))/(3)-2 sqrt(2)

Put each term in (sqrt(3))/(3)-2 sqrt(2) over the common denominator 3: (sqrt(3))/(3)-2 sqrt(2) = (sqrt(3))/(3)+(-6 sqrt(2))/(3):
(sqrt(3))/(3)+(-6 sqrt(2))/(3)

(sqrt(3))/(3)-(6 sqrt(2))/(3) = (sqrt(3)-6 sqrt(2))/(3):
Answer: | (sqrt(3)-6 sqrt(2))/(3)=1/sqrt(3)-2 sqrt(2)=- 2 sqrt(2) + 1/sqrt(3)

atan(5/12.5)=atan(0,4)=21,8°

show that 2/√(12)-√(8) can be written in the form √a +√b

1) Miguel needs to shave every morning

 2) Silvia want to put the clothes to go to training 

3) Adela and Anita needed makeup too

4) my sister and I want us to lie down at the same time

\(6\sqrt{37/4} = 1.4488506572121931\)

I think that is the reciprocal of owl .....

More about owls :)

sqrt3(27^2)

The tangent line is horizontal at x = a.

"The best argument that I could see against a "last" digit of an irrational number is that the concept of a "last digit" in an irrational number doesn't make sense, but that doesn't necessarily mean that it doesn't exist."

That sentence makes grammatical sense, but is semantic nonsense!  By definition, an irrational number doesn't have a last digit and hence there is no last digit!

The proof that pi is irrational was first demonstrated by Lambert in the 18th century.  There are several proofs which are more or less complicated (I wouldn't call any of them simple!) - see http://www.mathpages.com/home/kmath313.htm for example.  

It is Italian instructions for playing Classical music, and it means: "Very moderate tempo and with grace"

A ball is thrown at 40 degrees above the horizontal. The ball is in the air for 7.2 seconds before it hits. If it travels 47.0 meters before it hits the ground, what was the initial velocity of the ball?

Which kinematic equations are needed to find the horazontal and vertical components of the initial velocity?

F double sharp simply equals G........

It's OK that you don't get it.

22! = 1 x 2 x 3 x 4 x 5 x 6 x ...... x 22 .

Therefore the definition of n! is 1 x 2 x 3 x 4 x ........ (way until n.)

I would prefer doing it that way:

\(\color{orange}\dfrac{5}{6}\times 2.15 = \dfrac{5\times2.15}{6}=\dfrac{10.75}{6}=\dfrac{10.75 \times 4}{24}=\dfrac{43}{24}=1\dfrac{19}{24}\)

That is cookie coloured!! :)

Because there are 12 zeros after the 4 and 12 zeros after the 3, the product will have 12 + 12 = 24 zeros.

multiply the first two numbers : 4 x 3 = 12

Add the 24 zeros after it, Answer = 12,000,000,000,000,000,000,000,000. :)

Or if you need it in scientific notation, that is 1.2022644346 x 10^(-6)

We have the formula: (pH value) = - log (H+ value) <--- Here the log is in base 10.

Therefore we have the equation:

Let x 

5.92 = - log (x)

log (x) = -5.92

x = 10^(-5.92) approx. 0.0000012022644346

:) I think I know the answer.

Convert 1/7 into a hexadecimal number and give the first 10 digits:

1st Multiplication Iteration: 1/7 x 16 = 16/7 , Fractional Part = 2/7, Carry = 2

2nd M. I. : 2/7 x 16 = 32/7 , Fractional Part = 4/7, Carry = 4

3rd  M. I. : 4/7 x 16 = 64/7, Fractional Part = 1/7, Carry = 9

4th M.I. : 1/7 x 16 = 16/7 <----- You see it is repeating....... The hexadecimal fraction have the same nature as the decimal fraction.......

1/7 in hexadecimal system = 0.2492492492.........

First 10 digits.
