Answer:

x = 2.5

Step-by-step explanation:

Using the rule of exponents

[tex](a^m)^{n}[/tex] = [tex]a^{mn}[/tex]

Note that 4 = 2² and 32 = [tex]2^{5}[/tex], then

[tex](2^2)^{x}[/tex] = [tex]2^{5}[/tex], that is

[tex]2^{2x}[/tex] = [tex]2^{5}[/tex]

Since the bases on both sides are equal, equate the exponents

2x = 5 ( divide both sides by 2 )

x = 2.5
