That's a question about exponentiation.

Answer:

Kenji is wrong because he does not aply the porperty correctly.

Step-by-step explanation:

A exponetiation has this form:

$\boxed{a^b}$

<em>a </em>is the base

<em>b</em> is the power or exponent

To understand that situation it's important to know a property about exponentiation. When we have a multiplication with the same exponent and diferent bases, the result is the multiplication of the bases with the same exponent. Let's see this above, in mathematical language:

$\boxed{a^b \cdot c^b = (a\cdot c) ^b}$

Examples:

$2^3 \cdot 8^3 = (2 \cdot 8) ^3 = 16^3$

$10^9 \cdot 23^9 = (10 \cdot 23) ^9 = 230^9$

Now, we can say why Kenji is wrong. It's easy simplify $3^5 \cdot 4^5$ ! We know that the result is $(3 \cdot 4) ^5 = 12^5$ , but Kenji multiplied the bases and added the exponents, that's why he is wrong.
