Solution

3 \cdot 9^{2 x + 3} = 1

Solution

x = - \frac{7}{4}

+1

Decimal Notation

x = - 1.75

Solution steps

3 \cdot 9^{2 x + 3} = 1

Divide both sides by

3

9^{2 x + 3} = \frac{1}{3}

Apply exponent rules

2 (2 x + 3) = - 1

Solve

2 (2 x + 3) = - 1 : x = - \frac{7}{4}

x = - \frac{7}{4}

Popular Examples

5^{x-1}-5^x=-100

5^{x - 1} - 5^{x} = - 100

e^{(2x)}-e^{(x)}-12=0

e^{(2 x)} - e^{(x)} - 12 = 0

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

\frac{2 ^{x + 1}}{4 ^{x - 1}} = 2 x

e^{2 x} - x^{3} = 0

(1/2)^{(x-2)}+1=0

(\frac{1}{2})^{(x - 2)} + 1 = 0
