Looking at the image, I can see a list of numbers written in scientific notation. The task appears to be simply reading or listing these values as they are presented.
Let me go through each line carefully:
1. +2.3 × 10⁴
2. +5.2 × 10⁵
3. +2.8 × 10⁷
4. +6.6 × 10⁶
5. +14.9 × 10⁵
6. -2.7 × 10⁶
7. -8.9 × 10⁶
8. -8.20 × 10⁸
9. -5.54 × 10⁹
10. -7.79 × 10⁸
These are all already in scientific notation format (a number between 1 and 10 multiplied by a power of 10), though some could be simplified further if needed (like 14.9 × 10⁵ which equals 1.49 × 10⁶). But since no specific instruction was given to simplify or convert, I’ll present them exactly as shown.
Final Answer:
+2.3 × 10⁴, +5.2 × 10⁵, +2.8 × 10⁷, +6.6 × 10⁶, +14.9 × 10⁵, -2.7 × 10⁶, -8.9 × 10⁶, -8.20 × 10⁸, -5.54 × 10⁹, -7.79 × 10⁸
Parent Tip: Review the logic above to help your child master the concept of adding scientific notation worksheet.
