Unit 2 GMAS Review (2)

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 written as a product of a number (between 1 and 10) and a power of 10.

Front

How do you compare two numbers in scientific notation?

Back

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

Front

What is the formula for the area of a rectangle?

Back

The area of a rectangle is calculated using the formula: Area = length × width.

Front

How do you subtract numbers in scientific notation?

Back

To subtract numbers in scientific notation, ensure the exponents are the same. If they are not, adjust one of the numbers to have the same exponent, then subtract the coefficients.

Front

What is the square root of a number?

Back

The square root of a number is a value that, when multiplied by itself, gives the original number. For example, the square root of 9 is 3.

Front

What is the cube root of a number?

Back

The cube root of a number is a value that, when multiplied by itself three times, gives the original number. For example, the cube root of 27 is 3.

Front

What is the power of a power property in exponents?

Back

The power of a power property states that when raising a power to another power, you multiply the exponents. For example, (x^a)^b = x^(a*b).

Front

What is the product of powers property in exponents?

Back

The product of powers property states that when multiplying two powers with the same base, you add the exponents. For example, x^a * x^b = x^(a+b).

Front

What is the quotient of powers property in exponents?

Back

The quotient of powers property states that when dividing two powers with the same base, you subtract the exponents. For example, x^a / x^b = x^(a-b).

Front

How do you express a number in standard notation from scientific notation?

Back

To express a number in standard notation from scientific notation, move the decimal point to the right for positive exponents and to the left for negative exponents.
