Answer:
[tex]49a^2b^6[/tex]
Step-by-step explanation:
The given expression is:
[tex](7ab^3)^2[/tex]
Now, squaring the above expression, we get
=[tex](7)^2(a)^2(b^3)^2[/tex]
=[tex]49(a^2b^6)[/tex]
=[tex]49a^2b^6[/tex]
which is the required simplification of the given expression.
Thus, the correct simplification of the expression [tex](7ab^3)^2[/tex] is [tex]49a^2b^6[/tex].
