So, the math challengers aka the teachers have forced us to do math homework over the summer. And one of the things we have to learn about is scientific notation. However, the problem is none of the 7th grade teachers taught us that, and I have to crack the code quick so I can combat the Math challengers and the Exams Of Torturey and so I can tell everyone and hopefully get to meet a nice girl (yea, most girls at my school cant figure out the formula by themselves, they need some guys to teach them, and no guy has figured out, and Im gonna be the first to crack the safe and feel the power again!)

here are some beginner problems the challengers gave us so we can crack the code:

4. 1,300

5. 962,000

6. 63,000,000

10. 14,600

11. 8,900,000

12. 593,000,000

and even though I have a 100% chance of humiliatition of defeat from the Math Challengers, I feel pretty good about this.

NOW LETS CRUNCH SOME MATH PROBLEMS AND GET THAT CHALLENGER BASE!!!

In scientific notation all numbers are written in the form $$a \cdot 10^b$$

Any given integer can be written in the form $$a \cdot 10^b$$ in many ways: for example, 350 can be written as $$3.5\cdot 10^2$$ or $$35\cdot 10^1$$ or $$350 \cdot 10^0$$.

In normalized scientific notation, the exponent b is chosen so that the absolute value of a remains at least one but less than ten (1 ≤ |a| < 10). Thus 350 is written as $$3.5\cdot 10^2$$

 

4.   $$1300 = 1.3 \cdot 10^3\\
\hline$$

 

5.   $$962000 = 9.62 \cdot 10^5$$

 

6.   $$63000000 = 6.3\cdot 10^7$$

 

10. $$14600 = 1.46\cdot 10^4$$

 

11. $$8900000 = 8.9 \cdot 10^6$$

 

12. $$593000000=5.93\cdot 10^8$$
