Hi there!
<u><em>For this, we would be using PEMDAS:</em></u>
<u><em>Parentheses</em></u>
<u><em>Exponents</em></u>
<u><em>Multiplication (from left to right)</em></u>
<u><em>Division (from left to right)</em></u>
<u><em>Addition (from left to right)</em></u>
<u><em>Subtraction (from left to right)</em></u>
<u><em>1.Multiply all terms:</em></u>
<u><em>·</em></u>····
<u><em>2.Multiply the terms again:</em></u>
<u><em>·</em></u>··
<u><em>3.Subtract the terms:</em></u>
Therefore, the answer would be -7860.
