<em>Identify.</em>
<em>x</em> = 3
<em>y</em> = 28
xy - 538y + x⁶
<u>Step 2: Evaluate</u>
- Substitute in variables: 3(28) - 538(28) + 3⁶
- [Order of Operations] Exponents: 3(28) - 538(28) + 729
- [Order of Operations] Multiply: 84 - 15064 + 729
- [Order of Operations] Subtract: -14980 + 729
- [Order of Operations] Add: -14251
