Answer:
Step-by-step explanation:
So we know they had got $22,553 which is 90% more than last year. With this information we know:
190% = $22,553
1% = $22,553/190
1% = $118.70
100% = $11870
So overall it would be $11870 which they had got last year
<h3><u>The equivalent expression is:</u></h3>

<em><u>Solution:</u></em>
<em><u>Given expression is:</u></em>

We have to find the equivalent expression
We can simplify the above expression using law of exponents
<em><u>Use the following law of exponents:</u></em>

Therefore,

<em><u>Use another law of exponent</u></em>

Therefore,

Thus the equivalent expression is found
