See full question below.
Shkiper50 [21]

Answer:

<u>Solve the determinants first:</u>

  • B = 5*4 - 2*(-3) = 20 + 6 = 26
  • I = 1*1 - 0*0 = 1 - 0 = 1

<u>Find the following</u>

I.

  • B² = 26² = 676

II.

  • f(B + I) = f(26 + 1) = f(27)
  • f(27) = 4*27² + 3*27 - 5 = 2992

III.

  • f(B)² = f(26)² = f(676)
  • f(676) = 4*676² + 3*676 - 5 = 1829927

Reil [10]

Answer:

(3^2•2^2x^2y^4)

Step-by-step explanation:

Step  1  :

Equation at the end of step  1  :

 ((3xy3 • 2) • xy) • 6

Step  2  :

Equation at the end of step  2  :

 ((3•2xy3) • xy) • 6

Step  3  :

Multiplying exponents :

3.1    31  multiplied by  31   = 3(1 + 1) = 32

Multiplying exponents :

3.2    21  multiplied by  21   = 2(1 + 1) = 22
