3^(3/5) = 3^(.6) = about 1.933
-0.6x^2+3x+4 = 8 subtract 8 from both sides
-0.6x^2+3x-4 = 0 multiply both sides by -10/6
x^2 - 5x + 20/3 = 0 multiply both sides by 3
3x^2 - 15x + 20 = 0 this has no real solutions
[ The solutions are [ 15 plus/minus(sqrt 15) i ] / 6
5-38/6.3463+68 = about 67.01
8 /(2/5) =
8 x (5/2) = 40/2 = 20
If sin(theta) = - .7
Then csc(theta) = -1/.7
4 + 5/7 - 9/11 =
33/7 - 9/11 =
[11*33 - 7*9] / 77 =
[363 - 63] / 77 =
300 / 77 = 3 + 69/77
Let N = the "what" .....so we have.....
24 = .75N divide both sides by .75
32 = N
(4/11) / (12/13) =
(4/11) x ( 13/12) =
(4/12) x (13/11) =
(1/3) x (13/11) =
13/33
(5/3) x (7/1) = 35/3
(1/2)2
3/4 - 1/2
4 / 16
1/8 + 1/8
sqrt(1 / 16)
