Yeah exactly
no its 493
because its 22 to the 2nd power
no, if it was 22 to the second power it would look like \[(22)^2\]
this is (22)2, which means multiply 22 times 2

Let go Step by Step: Step 1. 8 * 3 = 32 (32 - 10)^2 + 9 Step 2. 32 - 10^2 = 22^2 = 22^2 + 9 Step 3. 22^2 = 484 = 484 + 9 = 493 Answer: 493
