Question

If a = 2b and b = 4c, then 3√a^2/16bc

Answer 1

Answer:

a = 2b

b = 4c

Find: ∛(a²/16bc)

substitute:

3√{(2b)²/(16×4c×c)}

3√{(4b²/64c²)}

3√(b²/16c²)

3√(b/16c)²......Square and square root gets camcelled.

3×(b/16c)

Again, substitute the value of b.

3×(4c/16c)

=3/4.

HOPE THIS HELPS :D
