To find out how much heavier an elephant is than a cat, we need to subtract the weight of a cat from the weight of an elephant.
Elephant weight = 1.15 * 10 ^ 4 pounds
Cat weight = 14 pounds
Hence, the difference in weight is:
1.15 * 10 ^ 4 pounds - 14 pounds
To subtract these numbers, we need to convert the weight of the cat to scientific notation:
14 pounds = 1.4 * 10 ^ 1 pounds
Now we can subtract:
1.15 * 10 ^ 4 pounds - 1.4 * 10 ^ 1 pounds
To subtract numbers in scientific notation, we need to have the same exponents (powers of 10). Let's convert the weight of the cat to have an exponent of 4:
1.4 * 10 ^ 1 pounds = 0.14 * 10 ^ 4 pounds
Now we can subtract:
1.15 * 10 ^ 4 pounds - 0.14 * 10 ^ 4 pounds
To subtract these numbers, we subtract the coefficients (1.15 - 0.14) and leave the exponent the same:
1.01 * 10 ^ 4 pounds
Therefore, an elephant is 1.01 * 10 ^ 4 pounds heavier than a cat.
