which expression is equal to 5.1 * 10 exponent-3

Answer 1

The expression \( 5.1 \times 10^{-3} \) can be written in decimal form. To convert it, you move the decimal point in 5.1 three places to the left (because of the negative exponent).

So,

\[ 5.1 \times 10^{-3} = 0.0051 \]

Thus, \( 5.1 \times 10^{-3} \) is equal to \( 0.0051 \).
