Answer 1

Dada la expresión algebraica la opción correcta es:

D) 24

Pasos

Si, a ⊕ b = (a+b)(a+2b)(a+3b)

Calcular 13[(8 ⊕ 2)/(4 ⊕ 2)]

Para el numerador:

a = 8

b = 2

Sustituir a y b;

(8 ⊕ 2) = (8+2)(8+2×2)(8+3×2)

(8 ⊕ 2) = (10)(8+4)(8+6)

(8 ⊕ 2) = (10)(12)(14)

(8 ⊕ 2) = 1680

Para el denominador:

a = 4

b = 3

Sustituir a y b;

(4 ⊕ 3) = (4+3)(4+2×3)(4+3×3)

(4 ⊕ 3) = (7)(4+6)(4+9)

(4 ⊕ 3) = (7)(10)(13)

(4 ⊕ 3) = 910

Sustituir numerador y denominador;

13[(8 ⊕ 2)/(4 ⊕ 2)]

= 13[(1680)/(910)]

= 13[24/13]

= 24
