SashulF [63]

Answer:

$n = -5$

Step-by-step explanation:

Given

$Digit = 0.000025$

Required

Rewrite using scientific notation, then find n

$Digit = 0.000025$

Express as fraction

$Digit =\frac{25}{1000000}$

This can be splitted to

$Digit = 25 * 10^{-6}$

The first number must be between 1 and 10; hence, 25 can be expressed as 2..5 * 10

$Digit = 2.5 * 10* 10^{-6}$

Apply law of indices

$Digit = 2.5 * 10^{1-6}$

$Digit = 2.5 * 10^{-5}$

Comparing n, the given options

$n = -5$
