Move the decimal point to the left until the number is between 1 and 10. Count how many places you move the decimal point.9,900 → 9.9

You moved the decimal point 3 places to the left. The power of 10 is 10 to the 3rd power

9,900 = 9.9 × 10 to the 3rd power

Find the LCM of k^2 + 3k + 2 and 2k^2 + 14k + 20.

Airida [17]

Answer:

C. 2(k +2)(k +5)(k +1)

Step-by-step explanation:

The LCM will be the product of unique factors.

$(k^2 + 3k + 2)=(k+1)(k+2)\\(2k^2 + 14k + 20)=2(k+2)(k+5)$

The unique factors are 2, (k+1), (k+2), (k+5), so the LCM is their product:

2(k+1)(k+2)(k+5) . . . . matches choice C
