Question

Calculate ( K ). Express your answer as a value in scientific notation to two significant figures, or as a calculation in terms of ( e ) raised to a power with a minimum of three significant figures.

( K = )

A. ( 3.14 × 10² )

B. ( 1.57 × 10² )

C. ( 6.28 × 10² )

D. ( 2.71 × 10² )

Answer 1

To solve for the value of K, the specific expression that K represents must be calculated using a calculator. The results should be expressed in proper scientific notation or as a power of e with at least three significant figures. Familiarity with the process of entering scientific notation into calculators is essential.

Step-by-step explanation:

To calculate the value of K, we must evaluate the given expressions using a calculator. We have been provided with several options, but without any additional context, it's unclear which specific calculation corresponds to the value of K. For now, assuming that the calculation of K involves one of these expressions, let's examine a few examples:

• For expression '456 × (7.4 × 10^8)', we would enter into the calculator and get the result in proper scientific notation.
• The calculation '(3.02 × 10^5) (9.04 × 10^15)' similarly requires multiplication and expressing the result in scientific notation.
• Expression '0.0044 × 0.000833' would be converted into scientific notation after multiplication to find the result.
• Lastly, '628 × 342' should be computed and expressed with the correct number of significant figures.

Regardless of the specific calculation, it's important to use a calculator and be familiar with entering numbers in scientific notation correctly to ensure the precision of your results.
