When you multiply powers with the same base, you sum the exponents:

So, in this case, you have

Answer:
<h2>4 is the right answer</h2>
<h2>2 × 2 = 4</h2>
<h3>2 × 1 = 2 </h3><h3>2 × 2 = 4</h3><h3>2 × 3 = 6 </h3><h3>2 × 4 = 8</h3><h3>2 × 5 = 10</h3><h3>2 × 6 = 12</h3><h3>2 × 7 = 14</h3><h3>2 × 8 = 16</h3><h3>2 × 9 = 18</h3><h3>2 × 10 = 20</h3>
<h2>Why is 2+2=4 and 2x2=4? </h2>
<h3>Originally Answered: why does 2*2=4 and 2+2=4? The truth is that a number multiplied by itself does not have to be equal to the same number added to itself. We can prove 2x2=4 easily. We have 2 groups of 2s.</h3>
Answer:
50%
Step-by-step explanation:
''What is the probability that she selected the biased coin?”
When we have n possible outcomes of an event and all of them have the same probability of appearance, then in theory each possibility has a probability 1/n of being the result of the event.
In this case the event is choosing randomly a coin out of 2, so no matter what the biased coin is or the results we get when we toss it, the probability of choosing the biased coin is ½ = 0.5 or 50%.
Answer:
y = s * 4
Step-by-step explanation:
You multiplied 4 to 3 to obtain 12:
x = 3 ; x = 3 * 4 ; x = 12
Therefore, if you multiply 4 to x, you must do the same to the other:
y = s
y = s * 4 is your answer.
