Explicación paso a paso:

Si: P(x) = 3x⁴⁷- 81x⁴⁴+5x-3

P(3) = 3(3)⁴⁷-81(3)⁴⁴+5(3)-3

P(3) = 3⁴⁸- 3⁴(4)⁴⁴ + 15 - 3

P(3) = 3⁴⁸-3⁴⁸ + 12

P(3) = 12

P(1) = 3(1)⁴⁷-81(1)⁴⁴+5(1)-3

P(1) = 3 - 81 + 5 -3

P(1) = -76

P(-1) = 3(-1)⁴⁷-81(-1)⁴⁴+5(-1)-3

P(-1) = -3 -81 - 5 -3

P(-1) = - 92

M = P(3) + P(1) - P(-1)

M = 12 - 76 - (-92)

M = - 64 + 92

M = 28
