Answer 1

The question involves converting from scientific to standard notation by moving the decimal point right for positive exponents and left for negative exponents. Examples include 7.11 × 10^-2 becoming 0.0711 and 9.18 × 10^2 becoming 918.

Step-by-step explanation:

The question asks about converting numbers from scientific notation to standard notation and identifying which conversions are true. Here are some examples demonstrated:

1. To convert 7.11 × 10^-2 to standard notation, we move the decimal point two places to the left, giving us 0.0711.
2. Converting 9.18 × 10^2 to standard notation involves moving the decimal two places to the right, resulting in 918.
3. For 3.09 x 10, we simply add one zero to the right of the decimal point since the exponent is 1, obtaining 30.9.

The process involves moving the decimal point to the right for positive exponents and to the left for negative exponents, according to the value of the exponent.
