To convert the scientific notation [tex]\( 2.15 \times 10^{-3} \)[/tex] to a standard numerical value, follow these steps:
1. Identify the base number: In this case, the base number is [tex]\( 2.15 \)[/tex].
2. Identify the exponent: The exponent in this case is [tex]\(-3\)[/tex].
3. Interpret the exponent: Since the exponent is negative ([tex]\(-3\)[/tex]), it indicates that the decimal point in the base number should be moved three places to the left.
4. Move the decimal point:
- Start with the base number [tex]\( 2.15 \)[/tex].
- Moving the decimal point three places to the left:
[tex]\[ 2.15 \rightarrow 0.215 \rightarrow 0.0215 \rightarrow 0.00215 \][/tex]
Thus, the value of [tex]\( 2.15 \times 10^{-3} \)[/tex] is [tex]\( 0.00215 \)[/tex].
