  2. Use a math strategy: Multiply the coefficients and add exponents for the same variable: 3 times 2 = 6 and 2 + 3 = 5.
  3. Check the result: Compare the result with the choices and check whether it is reasonable. The correct answer is 6x56x^5.

Multiply the coefficients and add exponents for the same variable: 3 times 2 = 6 and 2 + 3 = 5.

4. QuestionMultiple choice

Write 4.2imes1054.2 imes10^5 in standard form.

Please select an answer first.

Correct answer: D

The correct answer is 420000420000.

  1. Identify the quantities and operation: Read the numbers, units, model, table, or diagram carefully and identify what the problem asks you to find.
  2. Use a math strategy: Move the decimal point five places to the right to get 420,000.
  3. Check the result: Compare the result with the choices and check whether it is reasonable. The correct answer is 420000420000.

Move the decimal point five places to the right to get 420,000.

5. QuestionMultiple choice

What is 5−25^{-2}?

Please select an answer first.

Correct answer: A

The correct answer is 1/251/25.

  1. Identify the quantities and operation: Read the numbers, units, model, table, or diagram carefully and identify what the problem asks you to find.
  2. Use a math strategy: A negative exponent means the reciprocal: 5 to the negative 2 equals 1 divided by 5 squared, or 1/25.
  3. Check the result: Compare the result with the choices and check whether it is reasonable. The correct answer is 1/251/25.

A negative exponent means the reciprocal: 5 to the negative 2 equals 1 divided by 5 squared, or 1/25.

6. QuestionMultiple choice

Which expression is equivalent to 4(2x−3)+x4(2x-3)+x?
