Which of the following is the second greatest?
A) \(.000008\)
B) \(8*10^-^8\)
C) \(8 ÷ 10^5\)
D) \(\frac{.0008}{1000}\)
E) \(88 ÷ 10^6\)
A) \(.000008\)
B) \(8*10^-^8\)
C) \(8 ÷ 10^5\)
D) \(\frac{.0008}{1000}\)
E) \(88 ÷ 10^6\)
Let's write all the numbers in \(a*10^b\) form:
A. \(.000008\)=\(8*10^{-6}\)
B. \(8*10^{-8}\)
C. \(8 ÷ 10^5\)=\(8*10^{-5}\)
D. \(\frac{.0008}{1000}\)=\(8*10^{-4}*10^{-3}\)=\(8*10^{-7}\)
E. \(88 ÷ 10^6\)=\(8.8*10^{-5}\)
Descending order of magnitude: E>C>A>D>B
Ans. (C)

Which of the following is the second greatest?
get all of them in form 8*10^{-x}
A) \(.000008=8*10^{-6}\)
B) \(8*10^-^8=8*10^{-8}\)
C) \(8 ÷ 10^5=\frac{8}{10^5}=8*10^{-5}\)
D) \(\frac{.0008}{1000}=8*10^{-7}\)
E) \(88 ÷ 10^6=8.8*10^{-5}\)
So the choices in descending order : E, C, A, D, B
So Ans is C
