(-3)^{x-1}=729

Solution

(- 3)^{x - 1} = 729

Solution

x = 7

Solution steps

(- 3)^{x - 1} = 729

(- a)^{n} = b,

assuming

n

is even, solve

a^{n} = b

instead

Solve

3^{x - 1} = 729 : x = 7

Verify Solutions:

x = 7

True

The solution is

x = 7

Popular Examples

(1/(2^{x-4)})-(1/(2^{x-2)})=3

(\frac{1}{2 ^{x - 4}}) - (\frac{1}{2 ^{x - 2}}) = 3

4^{2} x + 8 = 3 (8^{x})

4^{x} = 64

4^{2x+1}+7(4^x)-15=0

4^{2 x + 1} + 7 (4^{x}) - 15 = 0

\frac{1}{3} = 2^{x}
