How do you simplify an expression in scientific notation?

Answer 1

To simplify an expression in scientific notation, first ensure that each term is expressed in the form (a \times 10^n), where (1 \leq a < 10) and (n) is an integer. Combine coefficients (the (a) values) by performing multiplication or addition as needed, while adjusting the exponent (n) accordingly. If you're multiplying, add the exponents; if you're dividing, subtract the exponents. Finally, if the coefficient is not in the proper range, adjust it by shifting the decimal point and modifying the exponent.
