Answer:
Moira's solution is not correct. The correct solution is [tex]6y^4+3y^4=9y^4[/tex]
Step-by-step explanation:
Given : [tex]6y^4+3y^4[/tex]
To simplify : [tex]6y^4+3y^4[/tex]
Solution : when we solve the given equation
Adding two like terms or similar terms
[tex]6y^4+3y^4=y^4(6+3)=9y^4[/tex]
The moira's solution is not correct because moira use multiplication rule not addition rule.
[tex]x^a\times x^b=x^{a+b}[/tex]
⇒ [tex]y^4\times y^4=y^{4+4}=y^8[/tex]
Therefore, correct solution is [tex]6y^4+3y^4=9y^4[/tex]
Answer:
Moira's solution is..... incorrect
6y4+3y4 is the same as...... (6*y^4) + (3*y^4)
9y8 is the same as...... 9y*y*y*y*y*y*y*y
6y4+3y4 simplifies to..... 9y^4
