# True or False :The number of terms in the expansion of $[(2x+y^3)^4]^7$ is $8$

$\begin{array}{1 1}(A)\;\text{True}\\(B)\;\text{False}\end{array}$

Toolbox:
• There are (n+1) terms in the expansion of $(x+y)^n$
$[(2x+y^3)^4]^7$
$\Rightarrow [(2x+y^3)]^{28}$
$\Rightarrow$ The number of terms =n+1=28+1=29
Hence the given statement is False.
