Question

Me ajudem rapido pfv

Sabendo que A= 2a, B = 3a³ e C = 6a², Calcule

a) A.B

b) B : C

c) 2A . 2B

d) ( 5C)²

Answer 1

Olá,

A = 2a
B = 3a³
C = 6a²

a) A*B = 2a*3a³
    A*B = 6a⁴

b) B:C = 3a³/6a²
    B:C = 1a³⁻²/2
    B:C = a/2

c) 2A*2B = 2*2a + 2*3a³
    2A*2B = 4a + 6a³
   2A*2B  = 2a(2+3a²)

d) (5C)² = (5*6a²)²
    (5C)² = 5²*(6²*a²*² )
    (5C)² = 25*(36*a⁴)
    (5C)² = 900a⁴

Bons estudos ;)
