Explain when you should reverse the inequality symbol when solving an equality.
rosijanka [135]
You must “reverse” the inequality sign to make the statement true: When you multiply by a negative number, “reverse” the inequality sign. Whenever you multiply or divide both sides of an inequality by a negative number, the inequality sign must be reversed in order to keep a true statement.

Which of the following correctly uses exponents to write "6 factors of 2"? A.62 B.26 C.6 ∙ 2 D.12
kotegsom [21]

Step-by-step explanation:

1. 6 factors of 2 means, 2 multiplied by itself 6 times.  It can be written in the form of exponents as 2⁶.

2. 2^m{\cdot} 2^n

The law of exponent is : x^a{\cdot} x^b=x^{a+b}

So,

2^m{\cdot} 2^n=2^{m+n}

The correct option is (A).

3. If the power of any number is 0, then the value of that number is equal to 1.

So,

23^0=1

Hence, this is the required solution.
