Answer:

x = 3

Step-by-step explanation:

When you multiply two exponents with the same base, you add the powers together. This means that

[tex]2^{4} *2^{5} =2^{9}[/tex]

This means that the equation is now

[tex]2^{9}=2^{3x}[/tex]

The first we need to do is remove the exponent. To do this, we have to take [tex]log_2[/tex] of each side to remove it

This gives us

[tex]3x=9\\\\x=3[/tex]
