Sample Question of the Day

Short answer📘 N.RN.A.2🧠 DOK 2

Question:

Simplify the expression (x^(1/3) * y^(1/6))^6 using the properties of exponents.

✅ Answer:
x^2 * y

💡 Explanation:

  • Using the properties of exponents, when raising a power to a power, you multiply the exponents.

  • Therefore, (x^(1/3))^6 = x^(1/3 * 6) = x^2 and (y^(1/6))^6 = y^(1/6 * 6) = y^1 = y.

  • Hence, the expression simplifies to x^2 * y.

Short answer📘 5.NBT.A.4🧠 DOK 3

Question:

A research scientist collected data about the weight of a rare insect species. One particular insect weighed 2.546 ounces. Use your understanding of place value to round this weight to the nearest tenth. Explain your rounding process and how place value understanding helps you decide where to round.

✅ Answer:
The weight of the insect rounded to the nearest tenth is 2.5 ounces. To round to the nearest tenth, look at the digit in the hundredths place, which is 4. Since 4 is less than 5, you do not round up. Therefore, the digit in the tenths place remains 5, and the digits after the tenths place are dropped. Understanding place value helps identify the significance of digits in each place, guiding the rounding process.

💡 Explanation:

  • Rounding requires understanding the value of digits in each place.

  • In this case, the tenths place is the target, and the decision to round up or not depends on the digit in the next smallest place, the hundredths.

  • Since the hundredths digit is less than 5, the tenths digit remains unchanged.

  • This process illustrates how place value understanding directs the rounding process.
