Answer
The statement does not make sense.
$$58 million =5.8\times10^{7}$$
$$58millionth = 5.8\times10^{-5}$$
Work Step by Step
Recall that 1 million = $1\times10^{6}$ and one millionth =$1\times10^{-6}$.
Thus,
$$58 million = 58(1\times10^{6})$$ $$=58\times10^{6}$$
Since the numerical factor has to be a number between 1 and 10, then this could be further expressed as:
$$=5.8\times10^{7}$$
While
$$58millionth = 58(1\times10^{-6})$$ $$58\times10^{-6}$$
Since the numerical factor has to be a number between 1 and 10, then this could be further expressed as:
$$=5.8\times10^{-5}$$
The statement does not make sense since the absolute value exponents in 10 are not equal.
