Jeremiah is factoring 0.64t^24 - 9 by using the rule, a^2 - b^2 = (a+b)(a-b). what will he use for the value of a? a.0.08t^12 b. 0.8t^12 c. 0.64 d. 0.8 i think it's b or !

to factor something with an exponent you need to take the square root of it 

 sqrt (0.64) = 0.8, sqrt(t^24) = t^12)

 Answer is B

if you explain the the question more correctly i might be able to answer this better
