Question

Express the following numbers in standard form:
0.000437 × 10⁴

Answer 1

To express a number in the standard form, move the decimal point such that there is only one digit to the left of the decimal point.
 0.000437 x 10⁴ = 4.37 x 10⁻⁴ x 10⁴ = 4.37 x 10⁰ = 4.37     (The decimal point is moved four places to the right.)
