3cos^6(x)+5<5

Solution

3 cos^{6} (x) + 5 < 5

Solution

No Solution for x \in R

Solution steps

3 cos^{6} (x) + 5 < 5

Subtract

5

from both sides

3 cos^{6} (x) + 5 - 5 < 5 - 5

Simplify

3 cos^{6} (x) < 0

Divide both sides by

3

3 cos^{6} (x) < 0

Divide both sides by

3

\frac{3 cos ^{6} ( x )}{3} < \frac{0}{3}

Simplify

cos^{6} (x) < 0

cos^{6} (x) < 0

If n is even,

u^{n} \geq 0

for all

u
