Q. Which sign makes the statement true?

\newline

1.3 \times 10^3 \,?\, 1.3 \times 10^2

\newline

Choices:

\newline

(A)

>

\newline

(B)

<

\newline

(C)

=

Exponents Comparison: We have $1.3 \times 10^3$ and $1.3 \times 10^2$ . $\newline$ Are the exponents the same or different? $\newline$ Exponents are $3$ and $2$ . $\newline$ Both exponents are different.
Different Exponents: Exponents are different. $\newline$ Which sign makes the statement true? $\newline$ $1.3 \times 10^3$ ____ $1.3 \times 10^2$ $\newline$ Compare the exponents because they are different. $\newline$ Exponents are $3$ and $2$ . $\newline$ $3 > 2$ $\newline$ $1.3 \times 10^3 > 1.3 \times 10^2$ .
