Answer :
Final answer:
B) 1.005 x 10^-3 is not equivalent to 100.5.
Explanation:
To determine which number is not equivalent to 100.5, we need to compare them in scientific notation. The number 100.5 in scientific notation is 1.005 x 10^2.
Option B, 1.005 x 10^-3, is significantly smaller than 100.5. It is equivalent to 0.001005. This is not equivalent to 100.5 and is therefore the correct answer.
Options A and C, 1.005 x 10^-2 and 100.5 x 10^-2 respectively, are equivalent to 0.01005 and 1.005, which are both significantly smaller than 100.5.
Option D, 100.5 x 10^-3, is equivalent to 0.1005, which is also smaller than 100.5.
In summary, option B, 1.005 x 10^-3, is the only choice that is not equivalent to 100.5.
