I'm sorry, but the people at 2.0calc will normally ignore these. Just letting you know, since this is a dumb question

yep.

I'm pretty sure its 1/5 & 1/200

Well, 4/5 of 10 is 8/10, and he shares them equally among 4 children, so therefore he gives 2 euro to each of his children.

I'm sorry, I can't help you unless I know what the problem is!

thats good! :)

Im good, and You?

It means two things, it can mean  the number before it is, is multiplied by itself so the number is squared  - this is if it comes after a number. For example. 6²  = 36

But if the ² comes after a length for example cm²  , it means the area is squared so if you have a area that is 2 cm X 2 cm, the area is 4 cm²

This and this

Arctan( x) means 'the angle whose tangent is x.'   So arctan is an angle.

Ex        arctan( 1 ) is the angle whose tangent is 1   =  45 degrees,  or in radians pi/4. 

             arctan (sqrt3)  is the angle whose tangent is sqrt(3)  = 60 degrees,  or pi/6  radians.

2,419,200nm =2.419 mm (millimeters)

4 weeks x 7 days x 24 hours x 60 minutes x 60 seconds=2,419,200nm

Try to solve for x algebraically. Isolate x by adding, subtracting, multiplying or dividing until x is by itself on the left side (make sure to do the same thing to both sides!).

2x-12 = 40    (add 12 to both sides)

2x = 52         (now divide both sides by 2)

x = 52/2 = 26

x = 26

To make sure this is right, go ahead and plug x = 26 back into the original equation:

2(26) - 12 = 40

52 - 12 = 40

See now that this works!

i forgot to type 10^(-6) meters

The answer is 19 this site is not for jokes its for math

Nope. I'm pretty sure they're all goats.

\(\sqrt[3]{16}\)= \(\sqrt[3]{8 x 2}\)= 2 \(\sqrt[3]{2}\)

BUT....they are all young boys.

Who is this???

Square root of negative 1 is mathematical letter "i"

Whatever 'my' age, as the question answerer, happens to be.
