f'(x) = 1/(2x3 + 5)
rewrite
f'(x) = (2X3 + 5) -1
use the chain rule
d/dx (2x3 + 5) - 1
-1 * (2x3 + 5)-2 * 6x2
- 6x2(2x3 + 5) -2
==================I would leave like this rather than rewriting this
4X2+X3+3X+7Y+2X3 can only be simplified to 3X3+4X2+3X+7Y, because X3 and 2X3 are the only like terms.
((2 plus (1 over 4)) plus 3) plus (7 over 8) = 6.12500
15 over 16
Two over eight plus four over eight plus one over eight equals seven over eight
1/5 plus 1/7 plus 3/10 is equal to 0.642857
4X2+X3+3X+7Y+2X3 can only be simplified to 3X3+4X2+3X+7Y, because X3 and 2X3 are the only like terms.
((2 plus (1 over 4)) plus 3) plus (7 over 8) = 6.12500
15 over 16
0.9375 or 15/16
Two over eight plus four over eight plus one over eight equals seven over eight
1/5 plus 1/7 plus 3/10 is equal to 0.642857
what is 75 over 2,980 plus 56 over 6,758
25 over 12
0.9375
One.
1/8 plus 1/4 plus 1/2 = 7/8 or 0.875
its going to be 4over 27 ----
