Answer:
Ada is correct.
Step-by-step explanation:
Problems with Naman:
Naman is supposed to follow PEMDAS, which is the order of operations, and stands for:
Parenthesis
Exponents (& Roots)
Multiplications
Division
Addition
Subtraction
~
The mistake: Naman moved +6 to the left and added it to the 2 located on the left side of the expression. You cannot do that, as it breaks the law of PEMDAS. On the other hand, Ada did the correct thing, which was to distribute 2 to all terms within the parenthesis (as one term in the parenthesis has a variable, and the other is a constant, meaning that they cannot be combined). This leads to Naman not doing the rest of the question correct.
Next, Ada correctly combined the two constants, which resulted in 0. 0 means nothing, therefore the placeholder is not needed. Therefore, 8x is the final answer.
The answer will be Addition Problem
Answer:
![xy^3 \sqrt[4]{y^3}](https://tex.z-dn.net/?f=xy%5E3%20%5Csqrt%5B4%5D%7By%5E3%7D)
Step-by-step explanation:
Recall the exponent property
.
We can use this property to break the problem down:
![\sqrt[4]{x^4y^{15}}=\sqrt[4]{x\cdot x\cdot x\cdot x\cdot y^3\cdot y^3\cdot y^3\cdot y^3\cdot y^3}=\boxed{xy^3 \sqrt[4]{y^3}}](https://tex.z-dn.net/?f=%5Csqrt%5B4%5D%7Bx%5E4y%5E%7B15%7D%7D%3D%5Csqrt%5B4%5D%7Bx%5Ccdot%20x%5Ccdot%20x%5Ccdot%20x%5Ccdot%20y%5E3%5Ccdot%20y%5E3%5Ccdot%20y%5E3%5Ccdot%20y%5E3%5Ccdot%20y%5E3%7D%3D%5Cboxed%7Bxy%5E3%20%5Csqrt%5B4%5D%7By%5E3%7D%7D)
That's simple, six upside down is 9, 5 upside down is 2, and 9 ipside down is two
