Q. Which sign makes the statement true?

\newline

7.7 \times 10^1

?

77

\newline

Choices:

\newline

(A)

>

\newline

(B)

<

\newline

(C)

=

\newline

Simplify expression: We have $7.7 \times 10^1$ and $77$ . Let's first simplify $7.7 \times 10^1$ . $\newline$ $7.7 \times 10^1 = 7.7 \times 10 = 77$ .
Compare expressions: Now we compare the simplified expression of $7.7 \times 10^1$ with $77$ . $\newline$ $77 ? 77$ $\newline$ Since both sides are equal, the correct sign is ＂ $=$ ＂.
Determine correct choice: We have determined that $7.7 \times 10^1$ is equal to $77$ , so the correct choice is $(C)=$ .
