In Exercises 31–50, perform the indicated computations. Write the answers in scientific notation. If necessary, round the decimal factor in your scientific notation answer to two decimal places.(6.1X10⁻⁸)(2X10⁻⁴)

Scientific notation is a way of expressing numbers that are too large or too small in a compact form. It is written as the product of a number (the coefficient) between 1 and 10 and a power of ten. For example, 6.1 x 10⁻⁸ represents 0.000000061. This notation simplifies calculations and comparisons of very large or very small values.

When multiplying numbers in scientific notation, you multiply the coefficients and add the exponents of the powers of ten. For instance, in the expression (6.1 x 10⁻⁸)(2 x 10⁻⁴), you would calculate 6.1 * 2 for the coefficients and add -8 and -4 for the exponents, resulting in 12.2 x 10⁻¹². This method streamlines the multiplication process.

Rounding in scientific notation involves adjusting the coefficient to a specified number of decimal places, typically one or two. This is important for maintaining precision while ensuring the number remains manageable. For example, if the result of a multiplication yields 12.2, rounding to two decimal places would keep it as 12.20, which is still in proper scientific notation format.
