Step-by-step explanation:
Answer:
<h3><u>2775</u> is the right answer.</h3>
Should be D. (5^2)^2= 5^4 (you multiply them) and 5^4+5^4=5^8
Matrix :
1 4 4
5 2 2
1 5 5
=> Determinant =
1 * (2*5 - 2*5) - 4 * (5*5 - 1*2) + 4 * ( 5*5 - 2*1)
= 1*(10 - 10) - 4*(25 - 2) + 4*(25 -2) = 1*0 + 4* 23 + 4*(25 - 2) = 0 - 4*23 + 4*23 = 0
Answer: 0
