Answer :

Answer: x = 1

Given:

[tex]3^{x+4}=243[/tex]

First, we need to express 243 as a number with base 3 raised to a certain exponent.

From this, if we take 3 to the fifth power, we will get the value of 243

[tex]3^5=243[/tex]

Now, we can rewrite the given equation as

[tex]3^{x+4}=3^5[/tex]

Now that we have the same base for both sides of the equation, we can now focus on solving the exponents for the value of x.

[tex]x+4=5[/tex]

*Solve for x

[tex]x=5-4[/tex][tex]x=1[/tex]

Therefore, the value of x = 1.
