Question 3.
Think about the answers to Problem 2(a–d). Explain the pattern used to find an answer when you multiply or divide a whole number by a power of 10.
Answer:- When multiply by power of 10 I will add zeroes on top of my whole number and that equals to my exponent.
In the similar way, when we divide by the power of 10 I will remove or subtract the zeroes on to my whole number and
that equals to my exponent.

Question 4.
Think about the answers to Problem 2(e–h). Explain the pattern used to place the decimal in the answer when you multiply or divide a decimal by a power of 10.
Answer:- When multiplying the decimal number by the power of 10, I will move the decimal number to the left side of
exponent and that make the number more value. In the similar way, When dividing the decimal number by the power
of 10, I will add or move the exponent number to the decimal value side and that makes the value lower one than the
actual one.

f. Explain how you found the unknown numbers in set (b). Be sure to include your reasoning about the number of zeros in your numbers and how you placed the decimal.
Answer:- The next number in the pattern had two zeroes, So the numbers were being divided by 100 which make it smaller by two numbers.
Likewise, we had continued to do all the numbers in same way.

g. Explain how you found the unknown numbers in set (d). Be sure to include your reasoning about the number of zeros in your numbers and how you placed the decimal.
Answer:-  The whole numbers were added one zero and continued so that means the whole numbers were being multiplied by 10. So, we had
multiplied the whole numbers by 10.

Question 6.
Shaunnie and Marlon missed the lesson on exponents. Shaunnie incorrectly wrote 10⁵ = 50 on her paper, and Marlon incorrectly wrote 2.5 × 10² = 2.500 on his paper.
a. What mistake has Shaunnie made? Explain using words, numbers, or pictures why her thinking is incorrect and what she needs to do to correct her answer.
Answer:- Shaunnie thinks that 10 power 5 means  10 x 5 which is 50 but 10 power 5 is 10 x 10 x 10 x 10 x 10 i.e., 100000.

b. What mistake has Marlon made? Explain using words, numbers, or pictures why his thinking is incorrect and what he needs to do to correct his answer.
Answer:- Marlon made the mistake by adding two zeroes at the end of the decimal number that had worked there, but 2.5 is a decimal number
he need to move the number to other point to two shifts making it as 250.
