haha,
how to solve 4*4+4*4+4-4*4=20
What do you find so difficult about this problem? Did you try to solve it? Start from the left:
16 + 16 + 4 - 16=20. +16 and -16 canecl out, so you have:
16 + 4=20
20=20. Was it that difficult?
tan (theta/ 2) = sqrt ( [1 - cos(theta)] / [ 1 + cos(theta)] ) = sqrt ( [ 1 - (4/5)] / [ 1 + (4/5)]) =
sqrt ( [1/5] / [ 9/5] ) = sqrt [ 1/9] = 1/3
Do all of the multiplications FIRST, then the + and -
16 + 16 +4 - 16 = 20
That would be 2.7
Since 1 mole of NaCl is 58.443 grams, it therefore follows that:
34.8g/58.443g=0.595......etc. moles of NaCl.
0.62
you read 34 boks
0/10
3.14159265
what is {21-3} divided by 3 to the second power
Nevermind, I found the answer!!!
Thanks no one!

3/4 times 3/1 equals 9/4 which is converted to 2 and a 1/4
What does the slant mean?
