Answer:
2
Step-by-step explanation:
The base B represents the number you multiply and the exponent "x" tells you how many times you multiply the base, and you write it as "B^ x." For example, 8^3 is 8X8X8=512 where "8" is the base, "3" is the exponent and the whole expression is the power.
 
        
                    
             
        
        
        
Answer:
2
Step-by-step explanation:
Simplify. Remember to follow PEMDAS and the left-> right rule. 
In this case, multiply the whole number (6/1) with the numerator (1)
6 x 1 = 6
Next, simplify by dividing 6 with 3: 
6/3 = 2
2 is your answer.

Our matrix C is the encoder.  Let X be our secret message and let B be our encoded message.  Therefore the relationship between the 3 can be represented as:
CX = B
So we want to solve for X (our secret message). So using matrix algebra:
X = C^-1*B
where C^-1 is the inverse of C.
C^-1 = | 3 -2 |
           |4 -3 |
So we take C^-1 and multiply it by matrix B to get X.  Matrix B is already given to us.  So just multiply those two.  I used a calculator to get:
X = | 20 8 5 3 15 12 15 |
      | 18 9 19 2 12 21 5 |
And since A = 1, B = 2, C = 3, etc....
We decode our message and it says:
X = | T H E C O L O |
      | R I S B L U E |
So the answer is: The color is blue (D)
