STEP 1

Assumptions1. The measurement is $70.09 \, \text{in}$

STEP 2

To determine the number of significant digits in a measurement, we need to understand the rules of significant figures.1. Non-zero digits are always significant.
2. Any zeros between significant digits are significant.
. Leading zeros are not significant.
4. Trailing zeros are significant only if the number contains a decimal point.

STEP 3

Now, let's apply these rules to our measurement $70.09 \, \text{in}$.

STEP 4

The number $70.09$ has four digits $7$, $0$, $0$, and $9$.

STEP 5

According to the rules, all non-zero digits are significant. So, $7$ and $9$ are significant.

STEP 6

The zero between $$ and $0$ is also significant because it is between significant digits.

STEP 7

The zero after the decimal point is significant because it is between significant digits.

So, all four digits in $70.09$ are significant.
Therefore, the number of significant digits in the measurement $70.09 \, \text{in}$ is4.
