a $10^1$
b $10^2$
c $10^3$

$76 \div 9 = 8$ remainder $4$, so it is $8\frac{4}{9}$

Step2: Evaluate the expression (PEMDAS)

First calculate parentheses: $5+4=9$
Then multiplication: $2\times9=18$, $3\times4=12$
Then subtraction: $18-12=6$

Step3: Convert feet to inches

1 foot = 12 inches, so $6\times12=72$ inches

Step4: Find power of 10

Count decimal shifts: $892.65$ to $892650$ shifts right 3 times, so $10^3$

Answer:

1. B. $8\frac{4}{9}$
2. A. 6
3. B. 72 inches
4. C. $10^3$
