Answer 1

See answer below

Explanation:

Hi there,

First checkbox, Second-to-last checkbox, and last checkbox are all valid expressions.

`2^(5) *2^(4) =2^(5+4) =2^(9)` based on a common algebraic rule
`x^(a) * x^(b) = x^(a+b)`

The first checkbox is just the stated answer.

The second-to-last answer is the same, as it can be rearranged as follows:

`2^(-2) *2^(11) =2^(-2+11) =2^(9)` 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;
`a^(5) = a*a*a*a*a`

Study well and persevere.

thanks,
