Original problem: log2(y-4) + log2y = 2
The first step is applying a log property to the first term which states that logbn + logba = logb(na)
So we can change the left side of the equation to log2[y(y-4)] or log2(y2-4y).
Then we apply another log property which states logbn = a is equivalent to ba = n
So we can change log2(y2-4y) = 2 to the equation 22 = y2-4yor 4 = y2 - 4y
Now we can swing the four around to make the quadratic y2 - 4y - 4 = 0
Unfortunately, whoever assigned you this problem decided to make it more difficult because the expression y2 - 4y - 4 is unfactorable, meaning you have to use the quadratic formula. With it, you should be able to find the two values for y: 2 ± √32/2
What else can I help you with?
How do you plus?
You use Plus as a symbol in Maths. Example, 2 Plus 2 equals 4. Or in symbols it would be 2+2=4. __________________________ Plus = + Equals = = (Equals equals =)
If 1 plus 1 equals 2 2 plus 2 equals 22?
no if 1 plus 1 equals 2 then 2 plus 2 equals 4.
2 plus 5 plus 3 equals 132 3 plus 6 plus 4 equals 380 4 plus 2 plus 7 equals 63 6 plus 3 plus 6 equals 228 8 plus 5 plus 2 equals?
No.
What is 2 plus 2 plus 1-1divided by 2 plus 8-6?
2 plus 2 equals 4plus1 equals 5minus 1 equals 4divided by 2 equals 2plus 8 equals 1010 minus 6 equals 4so it all equals to +_____29so its 29 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
1 plus 1 equals 2 plus 2 equals 4 plus 4 equals 8 plus 8 equals 16 plus 16 equals 32 plus 32 equals 64 plus 64 equals 128 plus 128 equals 256 plus 256 equals 512 plus 512 equals 1024 plus 1024 equals?

If 2 plus 3 equals 10 and 7 plus 2 equals 63 and 6 plus 5 equals 66 and 9 plus 7 equals 96 9 plus 7 equals what?
96
If 2 plus 3 equals 10 7 plus 2 equals 65 6 plus 5 equals 66 8 plus 4 equals 96 then what 9 plus 7 equals?
144
If 2 plus 3 equals 10 7 plus 2 equals 63 6 plus 5 equals 66 8 plus 4 equals 96 then 9 plus 4 equals?
26
2 plus 3 equals 10 and 7 plus 2 equals 63 and 6 plus 5 equals 66 and 8 plus 4 equals 96 Then 9 plus 7 equals?
If I am correct, 9 plus 7 equals 112.
If 2 plus 4 equals 10 3 plus 6 equals 45 5 plus 2 equals 43 7 plus 2 equals 89 9 plus 2 equals what?
Since 2 plus 4 is not 10, the "if" statement is false. Given a false "if", logically, 9 + 2 can equal anything you like.
