3^x(3^x-27)=0

3^{x} (3^{x} - 27) = 0

x = 3

Solution steps

3^{x} (3^{x} - 27) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

3^{x} = 0 or 3^{x} - 27 = 0

Solve

3^{x} = 0 :

No Solution for

x \in R

Solve

3^{x} - 27 = 0 : x = 3

x = 3

5 \cdot 2 0^{x} = 8 \cdot 2^{x}

t, f = a e^{- a t} u (t)

2^{4 x} - 5 \cdot 2^{2 x} + 4 = 0

9 \cdot 2 7^{x} = 27

1.7 = 240 (0.5)^{\frac{x}{19}}
