Answer: The correct options are .
Step-by-step explanation:
Desired factors = = 5 × m × m × n × n
Factors of given option are:
= m × m × m × m × m × n × n × n × n × n
= 5 × m × m × m × m × n × n × n
= 2 × 5 × m × m × m × m × n
= 3 × 5 × m × m × n × n
= 2 × 2 × 2 × 3 × m × m × m × n × n × n × n
Hence,the correct options are .
