Correct Answer: D

Rationale: To find the number of trees in each row: 1. Take the square root of the total number of trees: √65,536 = 256. 2. Since the number of rows equals the number of trees in each row, the correct answer is 256 (D). Choice A, 1684, is incorrect as it is not a factor of 65,536. Choice B, 1268, and Choice C, 668, are also incorrect as they do not satisfy the condition of having an equal number of rows and trees in each row.

Correct Answer: A

Rationale: To convert milliliters to liters, you divide by 1000 since there are 1000 milliliters in 1 liter. Therefore, 5000 milliliters divided by 1000 equals 5 liters. Choice A is correct as it accurately converts 5000 milliliters into liters. Choices B, C, and D are incorrect as they do not correctly convert the given milliliters to liters.

Correct Answer: C

Rationale: To find the new dosage after a 20% increase, we first calculate 20% of the original dosage: 20% of 100mg = 0.2 * 100mg = 20mg. Then, we add this to the original dosage: 100mg + 20mg = 120mg. Therefore, the new dosage is 120mg (Choice C). Choices A, B, and D are incorrect because they do not reflect the correct calculation for a 20% increase from the original dosage of 100mg.

Correct Answer: A

Rationale: To convert kilometers to meters, we need to multiply by 1000 since there are 1000 meters in 1 kilometer. Therefore, 3 kilometers x 1000 = 3000 meters. This is why choice A (3000 meters) is correct. Choices B, C, and D are incorrect because they do not follow the conversion factor of 1000 meters in 1 kilometer. Choice B (2000 meters) is too low, choice C (3500 meters) is too high, and choice D (2500 meters) is also too low.

Correct Answer: B

Rationale: To convert kilograms to grams, you need to multiply by 1000 since 1 kilogram is equal to 1000 grams. So, 4 kilograms x 1000 = 4000 grams. The correct answer is B. Choice A is incorrect as it only represents 1/10th of the correct value. Choice C is way too low and represents 1/100th of the correct value. Choice D is also significantly lower than the correct value.
