(- 3)^{x} = 87

No Solution for x \in R

Solution steps

(- 3)^{x} = 87

(- a)^{n} = b,

assuming

n

is even, solve

a^{n} = b

instead

Solve

3^{x} = 87 : x = \frac{ln ( 87 )}{ln ( 3 )}

Verify Solutions:

x = \frac{ln ( 87 )}{ln ( 3 )}

False

The solution is

No Solution for x \in R

x, (2^{2})^{x} - (3^{2})^{y} = 55

x, ((3^{x})^{5})^{y} = 225

(\frac{1}{2})^{a + 1} + (\frac{1}{2})^{a + 3} + (\frac{1}{2})^{a + 5} = 42

2^{x} \cdot 2^{1} - 6 = - 23 \cdot 2^{x} \cdot 2^{1}

19 2^{x} = 3.967
