Final answer:
The number 0.98 can be written as a binomial (1 - 0.02), where a equals 1 and b equals -0.02. In this context, the value for n is unnecessary as we're not dealing with an exponent.
Step-by-step explanation:
When asked to write 0.98 as a binomial, it can be expressed in the form (1 - 0.02). In this expression, a equals 1, b equals -0.02, and since there's no exponent implied here, n, which typically refers to the exponent in a binomial expression, is not relevant and can be considered nonexistent or equal to 1, as we're simply dealing with a single term of 1 and a second term of -0.02.
This approach is similar to basic algebra where you can express a number as the sum or difference of two parts, in this case as a binomial expression.
