Answer: 3

Step-by-step explanation:

[tex]\frac{2^5}{2^a}=2^2[/tex]

Multiply by [tex]2^a[/tex]

[tex]2^a*\frac{2^5}{2^a}=2^2*2^a[/tex]

[tex]2^5=2^2*2^a[/tex]

Divide by [tex]2^2[/tex] to isolate [tex]2^a[/tex]

[tex]\frac{2^5}{2^2}=\frac{2^2*2^a}{2^2}[/tex]

[tex]2^3=2^a[/tex]

Since we have the same base (2), we equal their exponents.

[tex]3=a[/tex]
