Given in the question,

a^5 * a^4 / a²

To find,

show working

<h3>Explanation</h3>

As we know that to divide exponents (or powers) with the same base, we subtract the exponents. Division is the opposite of multiplication, so when multiplying the exponents (or powers) with the same base add the exponents.

<h3>Working</h3>

a^5 * a^4 / a²

= a^(5 + 4) / a²  (Multiplying)

= a^9 / a²

= a^(9 - 2)          (Dividing)

= a^7  

<em>hence shown</em>
