Comparing Scientific Notation

Front

What is scientific notation?

Back

Scientific notation is a way of expressing numbers that are too large or too small to be conveniently written in decimal form. It is typically in the form of a x 10^n, where 1 ≤ a < 10 and n is an integer.

How do you compare two numbers in scientific notation?

Back

To compare two numbers in scientific notation, first compare the exponents. The number with the larger exponent is greater. If the exponents are the same, compare the coefficients.

Front

What is the significance of the exponent in scientific notation?

Back

The exponent indicates the power of ten by which the coefficient is multiplied, determining the scale of the number.

Front

How do you convert a number from standard form to scientific notation?

Back

To convert a number to scientific notation, move the decimal point in the number until only one non-zero digit remains to its left. Count the number of places the decimal has moved; this will be the exponent of ten.

Front

What is the relationship between the coefficients and exponents when comparing numbers in scientific notation?

Back

When comparing numbers in scientific notation, if the exponents are equal, the number with the larger coefficient is greater.

Front

How do you determine which of two numbers in scientific notation is larger when their exponents differ?

Back

When the exponents differ, the number with the larger exponent is the larger number.

Front

What does it mean if two numbers in scientific notation have the same exponent?

Back

If two numbers have the same exponent, their comparison depends solely on their coefficients.

Front

How can you express the number 0.00056 in scientific notation?

Back

0.00056 can be expressed in scientific notation as 5.6 x 10^-4.

Front

What is the scientific notation for the number 4500000?

Back

4500000 can be expressed in scientific notation as 4.5 x 10^6.

Front

How do you add or subtract numbers in scientific notation?

Back

To add or subtract numbers in scientific notation, first convert them to the same exponent, then add or subtract the coefficients.
