Explanation:

1) Step1: Calculate exponent first

$4^2 = 16$

1) Step2: Divide 15 by 3

$15 \div 3 = 5$

1) Step3: Add the two results

$16 + 5 = 21$

2) Step1: Calculate exponent first

$2^4 = 16$

2) Step2: Multiply 7 by the result

$7 \times 16 = 112$

2) Step3: Subtract 28 from the product

$112 - 28 = 84$

3) Step1: Calculate exponent first

$6^2 = 36$

3) Step2: Divide 92 by 4

$92 \div 4 = 23$

3) Step3: Subtract the results

$36 - 23 = 13$

4) Step1: Calculate exponent first

$3^3 = 27$

4) Step2: Multiply 2 by the result

$2 \times 27 = 54$

4) Step3: Add 10 to the product

$54 + 10 = 64$

---

5) Step1: Calculate exponent first

$5^2 = 25$

5) Step2: Multiply 25 by 6

$25 \times 6 = 150$

5) Step3: Subtract 85 from the product

$150 - 85 = 65$

---

6) Step1: Calculate exponent first

$2^3 = 8$

6) Step2: Divide 64 by the result

$64 \div 8 = 8$

6) Step3: Add 24 to the quotient

$8 + 24 = 32$

---

7) Step1: Calculate exponent first

$2^3 = 8$

7) Step2: Divide 70 by 5

$70 \div 5 = 14$

7) Step3: Subtract the results

$14 - 8 = 6$

---

8) Step1: Calculate exponent first

$4^2 = 16$

8) Step2: Multiply 7 by 2

$7 \times 2 = 14$

8) Step3: Add the two results

$16 + 14 = 30$

---

9) Step1: Calculate exponent first

$3^2 = 9$

9) Step2: Multiply 2 by the result

$2 \times 9 = 18$

9) Step3: Add 1 to the product

$18 + 1 = 19$

---

10) Step1: Calculate exponent first

$4^2 = 16$

10) Step2: Divide 80 by the result

$80 \div 16 = 5$

10) Step3: Add 7 to the quotient

$7 + 5 = 12$

1. $21$
2. $84$
3. $13$
4. $64$
5. $65$
6. $32$
7. $6$
8. $30$
