Hi,

We can start finding the square root of both sides.

Qty A: All the number in A are square so, 2x3x5x7x11=2310
Qty B: 2310

Qty A= Qty B

IMO C

Hope this helps!

All the terms inside Quantity A's square root are perfect squares already.
So to compute Quantity A, just multiply the roots of the terms under the square root.
Which results in 2310.
This is the same as Quantity B - Hence C
