Quick steps to solve this.
1. Lets square both. (X +Y)*2 = 7*7
2. Then, X*2 + 2XY + Y*2 = 49
3. Since XY is given to 4, X*2 + 8 + Y*2 = 49
4. Move 8
5. X*2 + Y*2 = 49 - 8
6. X*2 + Y*2 = 41
The answer is "41" Boom!
Answer:
(2^2)^3/2 = (2)^3 = 8
Step-by-step explanation:
So to solve (4)^3/2 ,you have to realise that you need to remove the denominator in the exponent value which in this case is 2
In order to remove the 2,you would need a 2 in the numerator of the exponent .While understanding all this the value 4 can be equated as 2^2.
Thus your means of getting a 2 in the numerator is solved by simply replacing the 4 with 2^2
Thus what you will get is (2^2)^3/2
Now we have a property in exponent where
(x^m)^n = (x)^mn
Thus (2^2)^3/2 = (2)^3 =8
Answer:
-49x - 18 is the final answer!
