Question

3^x+3^x+3^x=243 what is the value of x

Answer 1

3^x (1+1+1) = 243
3^x =243/3
3^x = 81
3^x = 3^4
on comparing the exponents of both sides
x = 4

Answer 2

$<b >Hey here is your answer$

$= {3}^{x} + {3}^{x} + {3}^{x} = 243 \\ \\ = {3}^{x} (1 + 1 + 1) = 243 \\ \\ = 3 \times {3}^{x} = 243 \\ \\ = {3}^{x} = \frac{243}{3} \\ \\ = {3}^{x} = 81 \\ \\ = {3}^{x} = {3}^{4}$
On comparing the component of both sides
$\\ = x = 4$
hope this helps you
