Question

(3² • 3³ • 3⁴ ) ² =

( 3y + 2z )² =

(5m³ + 7m² - 8m+ 4 ) (2m) =

(4c+8) - (-2c + 10 ) =​

Answer 1

(3² • 3³ • 3⁴ ) ² = 3²*³*⁴ = 3⁹ (los exponentes se suman)

                            (3⁹)² = 3¹⁸ (los exponentes se multiplican)

( 3y + 2z )² =  (3y)² + 2(3y)(2z) + (2z)²   (binomio al cuadrado)

                 =    9y² + 12yz + 4z²

(5m³ + 7m² - 8m+ 4 ) (2m) = 10m⁴ + 14m³ - 16m² + 8m

(4c+8) - (-2c + 10 ) =​ 4c + 8 + 2c - 10 (ley de signos)

                             = 6c - 2
