How do i solve 1? Rewriting the equation so that you set up a one to one correspondence between all of the parts. Then solve for x

Answer: x = 1

Given:


3^(x+4)=243

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


3^5=243

Now, we can rewrite the given equation as


3^(x+4)=3^5

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.


x+4=5

*Solve for x


x=5-4
x=1

Therefore, the value of x = 1.

To check:


3^(x+4)=243
3^((1)+4)=243
3^5=243
243=243

To check
