Answer:
C. [tex](9\times 8)\times 5[/tex]
Step-by-step explanation:
Associativity : multiplication is associative that is [tex]x\times (y\times z)=(x\times y)\times z[/tex]
Hence [tex]9\times (8\times 5)=(9\times 8)\times 5[/tex]
Check :
[tex]9\times (8\times5)=9 \times40=360\\\\(9\times8)\times 5=72\times5=360\\\\9\times(8\times5)=(9\times8)\times5[/tex]
