Answer is 5^12 which is choice A (assuming you meant to put the ^ symbol)
The bases are the same (both are 5), so you add the exponents: 4+8 = 12. The base stays the same the entire time.
So, 5^4*5^8 = 5^(4+8) = 5^12
So whats the rest of this question? its uncompleted.
I think it’s A.I’m sorry not that sure
It is an arithmetic series
Your zeroes are x=-2, x=sqrt 3 i, and x=-sqrt3 i
