Yes, his estimate is reasonable. But only if Michael is less than 2 years old.
4x^2 - 2xy^2
5xy^2 +
3x^2y
_____________
12x^5y^4-2xy^2
This is so because 4+5+3 is 12, then using laws of indices to add your x and y you get x^5 and y^4
To simplify your answer to the lowest you have it in the form of
3x^2y^2(4x^2y - 2xy^2)
If you multiply this as well you get the same answer I got with the addition
Actually, yes, it is possible for two different numbers to give the same result when squared.
In my last answer, I wrote that it wasn't, but I realize now where my mistake was made.
When a number like positive 4 is squared, the answer is 16. When a number like negative 4 is squared, the answer is also 16. I think that the only time when two different squared numbers have the same result is when they are the same number but have a different positive/negative sign.
I hope this helps.
Using PEDMAS, you would divide I/2 first, then add 2 to that and subtract I from the equation. It all varies on what "i" is, however.
Answer: <span>Qualitative/nominal
Gender is expressed as qualitative and nominal. Qualitative because it doesn't have a number, so it's not quantitative. It also nominal because gender is considered as having the same level. Another example of nominal is blood group or religion.
If it has an order of level(example: severity mild to severe), it will be ordinal.</span>
