Question 6 Which expression is NOT equivalent to a b3 ? ? o ab - ab Tan- 1 [ ba ) ᏣᏩᎾ Answer:|

Answer 1

The expression that is not equivalent to the given expression is;

`a^4b^4-ab`

Step-by-step explanation:

Let us simplify each of the given expression to find the one that is not equivalent to the given expression.

`\begin{gathered} (a^2b)(b^2a) \\ =a^2* a* b* b^2 \\ =a^3b^3 \end{gathered}`
`\begin{gathered} a^4b^4-ab \\ \text{cannot be simplified further.} \end{gathered}`
`((a^2b^2)^2)/(ab)=(a^4b^4)/(ab)=a^3b^3`
`\begin{gathered} (ab)(ba)(ab)=a* a* a* b* b* b \\ =a^3b^3 \end{gathered}`

The only expression that cannot be simplified to the given expression is;

`a^4b^4-ab`

Therefore, the expression that is not equivalent to the given expression is;

`a^4b^4-ab`
