mammal\tweight (pounds)
african elephant\t1.44×10⁴
blue whale\t2.87×10⁵
fin whale\t9.92×10⁴
right whale\t8.82×10⁴
white rhinoceros\t7.94×10³
the weighs more because

Explanation:

Step1: Compare the weights

We compare the weight of the blue whale $2.87\times 10^{5}$ pounds and the white rhinoceros $7.94\times 10^{3}$ pounds.

Step2: Analyze the powers of 10

$10^{5}=100000$ and $10^{3} = 1000$. The blue - whale's weight has a higher power of 10. Also, $2.87\times 10^{5}=287000$ and $7.94\times 10^{3}=7940$.

Answer:

Blue Whale; $2.87\times 10^{5}>7.94\times 10^{3}$
