Question

How do I solve for x

Answer 1

Answer:

x=2

Step-by-step explanation:

27^x could also be written as 3^3x because 27 is 3^3. From here you know 3^x+4 is 3^3x. x+4 is 3x.With basic algebra you can find that x is 2

Answer 2

Answer:

x= 2

Step-by-step explanation:

consider

27 = 3³

__________________________

${3}^{x + 4} = {27}^{x}$

${x}^{x + 4} = ( {3}^{3} )^{x}$

${3}^{x + 4} = {3}^{3(x)}$

${3}^{x + 4} = {3}^{3x}$

$x + 4 = 3x$

$4 = 3x - x$

$4 = 2x$

$\frac{4}{2} = x$

$2 = x$
