From the power rules, the matching of each expression with its equivalent expression is:
<h3>Power Rules</h3>
There are different power rules, see some them:
1. Negative exponent. For this rule when you have a negative exponent, you need to invert the number, i.e, the power base is converted to the denominator. After that, you should solve the power with a positive exponent. See the examples:
2. Power. For this rule, you should repeat the base and multiply the exponents. See the example, .
3. Zero Exponent. When you have an exponent equals to zero, the result must be 1. See the example, .
From this for your question, you have:

Base edge squared +2times base edge √ base edge squared over 4 + height squared
1. 30$ because 30% of $100 is 30$
2. 30%. 10% is 12•3
No it’s not -7 it’s = 2x + 20
