Question

than 1.
if q is a single-digit number, then $q \times 10^{-5}$ is always negative.
?
true
false

Explanation:

Step1: Define single-digit numbers

Single-digit numbers include positive values (1-9), zero, and negative values (-1 to -9).

Step2: Test positive single-digit q

Take $q=5$, calculate $5 \times 10^{-5} = 0.00005$, which is positive.

Step3: Evaluate the statement

Since there exist single-digit q where $q \times 10^{-5}$ is positive, the claim that it is "always negative" is false.

Answer:

False
