Solution:
Given that,
[tex]\text{Weight of humming bird brain } = 2.04 \times 10^{-3}\ ounces[/tex]
[tex]Weight\ of\ elephant\ brain } = 1.76 \times 10^2\ ounces[/tex]
How many times heavier is the elephant's brain than the hummingbird's brain?
Let "x" be the number of times the elephant's brain is heavier than hummingbird's brain
Therefore,
[tex]Weight\ of\ elephant\ brain } = x \times \text{Weight of humming bird brain }[/tex]
[tex]1.76 \times 10^2\ = x \times 2.04 \times 10^{-3}\\\\x = \frac{1.76 \times 10^2}{2.04 \times 10^{-3}}\\\\x = 0.8627 \times 10^{ 2 + 3}\\\\x = 0.8627 \times 10^5\\\\x = 86270[/tex]
Thus, elephant's brain is 86270 times heavier than hummingbird's brain
