Answer:
See answer below
Step-by-step explanation:
Hi there,
First checkbox, Second-to-last checkbox, and last checkbox are all valid expressions.
[tex]2^{5} *2^{4} =2^{5+4} =2^{9}[/tex] based on a common algebraic rule [tex]x^{a} * x^{b} = x^{a+b}[/tex]
The first checkbox is just the stated answer.
The second-to-last answer is the same, as it can be rearranged as follows:
[tex]2^{-2} *2^{11} =2^{-2+11} =2^{9}[/tex] based on the same algebraic rule above, applies for negative numbers as well!
The last checkbox is simply the definition of an exponent; each exponent has been expanded; [tex]a^{5} = a*a*a*a*a[/tex]
Study well and persevere.
thanks,
