Answer :

Certainly! Let's solve the equation step by step:

[tex]\[ 4 \cdot 3^{0.2x} = 5 \][/tex]

1. Isolate the exponential term:
Start by dividing both sides of the equation by 4 to isolate the exponential term.

[tex]\[ 3^{0.2x} = \frac{5}{4} \][/tex]

2. Convert to a logarithmic equation:
To solve for [tex]\( x \)[/tex], we can take the natural logarithm (ln) of both sides of the equation.

[tex]\[ \ln(3^{0.2x}) = \ln\left(\frac{5}{4}\right) \][/tex]

3. Apply the power rule of logarithms:
Use the property of logarithms that [tex]\( \ln(a^b) = b \ln(a) \)[/tex].

[tex]\[ 0.2x \cdot \ln(3) = \ln\left(\frac{5}{4}\right) \][/tex]

4. Solve for [tex]\( x \)[/tex]:
To isolate [tex]\( x \)[/tex], divide both sides of the equation by [tex]\( 0.2 \cdot \ln(3) \)[/tex].

[tex]\[ x = \frac{\ln\left(\frac{5}{4}\right)}{0.2 \cdot \ln(3)} \][/tex]

5. Calculate the numerical value:

After substituting the numerical values into the equation, we solve for [tex]\( x \)[/tex].

Therefore, the solution to the equation is:

[tex]\[ x \approx 1.01557006787506 \][/tex]

So, the value of [tex]\( x \)[/tex] that satisfies the equation [tex]\( 4 \cdot 3^{0.2x} = 5 \)[/tex] is approximately [tex]\( 1.01557006787506 \)[/tex].
