Since the values are the same on both sides the matrix value is a=1
Let log5 125 = x
Removing log you get 5^x = 125
Rewrite 125 as 5^3
Now 5^x = 5^3
x = 3
value of x is: x= i and x= -i
Step-by-step explanation:
We need to find the value of x from
using quadratic formula.
The term is: 
The quadratic formula is:

Where a = 1, b=0,c=1
Putting values:

So, value of x is: x= i and x= -i

The next number would be 4 because you add 1, then, subtract 2, add 3, subtract 4, meaning you would add 5 to -1 and get 4
The answer is 4
