Question

A.b^2=12
b.c^2=16
c.a^2=9
a.b.c=?

Answer 1

12

Explanation:

(a.b^2)×(b.c^2)×c.a^2 = 12×16×9 = 1 728

then

a^3×b^3×c^3 = 1728

then

(abc)^3 = 1728

then

abc = 12

Answer 2

Explanation:

(a.b²)*(b.c²)*(c.a²) = 12 * 16 * 9

a³*b³*c³= 4*3 * 4*4 *3*3

(abc)³ = 4³ * 3³

(abc)³ = (4*3)³

(abc)³ = (12)³

Therefore,

abc = 12
