Multiplying two numbers in scientific notation

The video tutorial explains how to multiply numbers in scientific notation by multiplying the coefficients and adding the exponents. It demonstrates the multiplication of decimal numbers, emphasizing the importance of adjusting decimal points based on place values. The tutorial also addresses correcting the format of scientific notation when the result exceeds a single-digit coefficient.

What is the first step when multiplying numbers in scientific notation?

• Add the coefficients

• Multiply the exponents

• Multiply the coefficients

• Subtract the exponents

When multiplying 7.8 and 1.7, what is the result before adjusting for decimal points?

• 13.26

• 1.326

• 1326

• 132.6

How many decimal places are considered when adjusting the result of 7.8 * 1.7?

• 1

• 4

• 2

• 3

Why is it necessary to adjust the decimal point in the final result of a multiplication in scientific notation?

• To match the original numbers

• To ensure the coefficient is less than 10

• To make the number larger

• To simplify the calculation

What adjustment is made to the exponent when the decimal point is moved in scientific notation?

• The exponent is decreased

• The exponent remains the same

• The exponent is increased

• The exponent is doubled
