almond37 [142]

Answer with explanation:

|A| = -2

|B|= -3

|C| = -4

$|4 C^TA^{-1}C^TB^{3}|=4 |C||A|^{-1}|C||B|^3, \text{as}|C^T|=|C|,|A^n|=A^n\\\\=4 \times (-4) \times (-2)^{-1} \times (-4) \times (-3)^3\\\\=4 \times (-4) \times \frac{-1}{2} \times (-4) \times (-27)\\\\=-1728 \times \frac{-1}{2} \\\\=864$

I really need help!!!!

kow [346]

Answer:

${b}^{9}$

Step-by-step explanation:

One of the rules for division of powers is that:

$\frac{ {a}^{m} }{ {a}^{n} } = {a}^{m - n}$

Knowing this:

$\frac{ {b}^{11} }{ {b}^{2} } = {b}^{11 - 2} = {b}^{9}$
