<h2>169</h2>
In this problem, we need to use squaring method.
5² means 5 × 5
5² = 25
12² means 12 × 12
12² = 144
So, simplify these statements:
5² × 12²
25 + 12² (Simplify 5², which means 5 × 5)
25 + 144 (Simplify 12², which means 12 × 12)
We get the answer:
25 + 144 =
<h3>169</h3>

what's the question???
Step-by-step explanation:
Its Dr. Appiah’s patients’ ages vary less than do Dr. Singh’s patients’ ages and <span>Dr. Cantwell’s patients’ ages and Dr. Singh’s patients’ ages vary about the same amount.</span>
(4^2 + 7) * 4 - 5 + 7
<em><u>Parentheses first.</u></em>
23 * 4 - 5 + 7
<em><u>Multiplication.</u></em>
92 - 5 + 7
<em><u>Subtraction.</u></em>
87 + 7
<em><u>Addition.</u></em>
94 is the final answer.
