Question

express 7.25 in scientific notation.
?×10^?
hint: if the decimal doesnt move, what power must the exponent be?
enter the coefficient in the green box and the exponent in the yellow box.

Explanation:

Step1: Recall scientific notation rules

Scientific notation is in the form \( a \times 10^{n} \), where \( 1 \leq |a| < 10 \) and \( n \) is an integer. For a number like \( 7.25 \), since the decimal point doesn't need to move (it's already between 1 and 10), the coefficient \( a \) is \( 7.25 \) and the exponent \( n \) is \( 0 \) (because \( 10^{0}=1 \), and \( 7.25\times1 = 7.25 \)).

Step2: Determine coefficient and exponent

The coefficient \( a \) is \( 7.25 \) and the exponent \( n \) is \( 0 \).

Answer:

\( 7.25\times10^{0} \)
