(0,5)^(3x-18)>=4^(2x-6) inequation

You have entered [src]

 18 - 3*x     2*x - 6
2         >= 4

$$\left(\frac{1}{2}\right)^{3 x - 18} \geq 4^{2 x - 6}$$

(1/2)^(3*x - 18) >= 4^(2*x - 6)

Rapid solution 2 [src]

(-oo, 30/7]

$$x\ in\ \left(-\infty, \frac{30}{7}\right]$$

x in Interval(-oo, 30/7)

Rapid solution [src]

x <= 30/7

$$x \leq \frac{30}{7}$$

x <= 30/7
