if the number 0.000088 is written in scientific notation, it will be in the form 8.8 × 10^n. what is the value of n?
select the correct answer below:
n = 7
n = 4
n = -5
n = -7
n = 5
n = -4

Explanation:

Step1: Recall scientific notation rule

Scientific notation is \(a\times10^{n}\), where \(1\leqslant|a|\lt10\). For \(0.000088\), move the decimal point.

Step2: Move the decimal point

Move the decimal point in \(0.000088\) 5 places to the right to get \(8.8\). Since we move the decimal point to the right for a number between \(0\) and \(1\), \(n=- 5\).

Answer:

\(n = - 5\)
