I believe the converse is: if 2x equals 6 then x equals 3 inverse: if x doesn't equal 3 then 2x doesn't equal 6 contrapositive: if 2x doesn't equal 6 then x doesn't equal 3
Assuming y' is dy/dx, y = x^4/4 + yx^2
3+10 = 13
18
y = 6 x 3.5; If you can't do that in your head, split it up: 6 x 3 = 18, 6 x .5 = 3, 18 + 3 = 21
2 to the power of -3 equals 0.125
2 to the power of -3 equals 0.125
If m equals 3 then m to the 6th power (m6) equals 36 or 3 x 3 x 3 or 27
-32 equals 9
3 times 3 times 2 equals 18
6 times 3 equals 18
78
3x=18 x=18/3 x=6
Three to the 4th power divided by 3 to the 7th power equals 0.03703703703
if and x equal -18 find y -18 * 1/3 = -6
3^18 is equal to 387,420,489.
pq-r, if p is 3, q is 4, and r is -6 is equal to 3 x 4 - (-6), which is equal to 12 + 6, which is equal to 18.
