Did either student simplify the expression correctly? If so, tell who and explain how her work follows the laws of exponents.
If neither student is correct, simplify the expression and explain how it follows the laws of exponents.
Since the expression is $2^4 \cdot 2^3$, we can simplify it by adding the exponents together since the base is the same.
Student A: $2^4 \cdot 2^3 = 2^{4+3} = 2^7$
So, student A simplified the expression correctly by following the law of exponents that states when you multiply two terms with the same base, you add the exponents.
Therefore, student A simplified the expression correctly.
