*Question*

**Find the number of zeros in following expression****13 * 15 * 22 * 125 * 44 * 35 * 11**

**Step 1: Do the Factor representation**

**Step 2:**

For number of zeros in expression, look at the number of **possible pairs of (2 * 5)**

If you look above you will observe that only three pairs of (2 * 5) are possible

That is **(2*5) * (2*5) * (2*5)**

Hence in the expression there **will be three zeros**
