Final answer:
The standard notation of 7.23 x 10⁻⁶ is 0.00000723, which is achieved by moving the decimal point six places to the left because the exponent is negative.
Step-by-step explanation:
The standard notation of 7.23 x 10⁻⁶ is written by moving the decimal point six places to the left, because the exponent is negative. The result is 0.00000723. In standard notation, numbers are not written with exponents, so the power of ten is not present. This process allows for the expression of very small or very large numbers in a more digestible form without the use of scientific notation.
Examples:
- a. 7.11 × 10⁻² becomes 0.0711.
- b. 9.18 × 10² becomes 918.
- c. 3.09 x 10⁻³ becomes 0.00309.
