Answer:
x = 3
Step-by-step explanation:
Before we begin, remember the following:
x√a + y√a = (x+y)√a
√xy = √x * √y
The given equation is:
+
=
Now, we know that:
48 = 16*3
Therefore:
can be written as
We also know that:
Therefore:
Now, substitute with the above in the given equation, this will give us:
+
=
x(
Based on the rules mentioned earlier, we can conclude that:
4x + 4 = 16
4x = 16-4
4x = 12
x = 3
Hope this helps :)
