Q. Which sign makes the statement true?

\newline

2.5 \times 10^1

?

52

Choices:

\newline

(A)

>

\newline

(B)

<

\newline

(C)

=

Write Expressions: Write down the expressions to compare. $\newline$ We have $2.5 \times 10^1$ and $52$ . $\newline$ We need to determine which sign makes the statement true: $2.5 \times 10^1 \, ? \, 52$ .
Convert to Standard Form: Convert the scientific notation to standard form. $2.5 \times 10^1$ is the same as $2.5 \times 10$ , which equals $25$ . Now we compare $25 ? 52$ .
Compare Numbers: Compare the two numbers. $\newline$ Since $25$ is less than $52$ , the correct sign is $<$ . $\newline$ $25 < 52$ .
