The solution of cube = 81 of 3x

The solution of cube = 81 of 3x


Cube of x = 27
So, x = 3



Given that the quintic power of 64 △ the cubic power of 8 = the x power of 2, find X


That is, 6 * 5-3 * 3 = X
x=21



(1)x3-729=0 (2)216x3+1=0 (3)x+5)3+27=0 (4) ( 8- 0.1x)3+0.027=0
Find the value of X


9 -1/6 -8 83
