Could you explain that a bit more simply please?

 

Changing the order of factors does not change the product,
i.e. if a and b are two real numbers, then ab=ba .

 

12m75n84p420m56n4=1254206m7n8p4m5n4=1254620m7n8p4m5n4=1265420m7n8p4m5n4=1262020m7n8p4m5n4|126=22020=1=21m7n8p4m5n4=2m7n8p4m5n4=2m7m5n8n4p4

 

 Formula Quotient rule with same base: anam=anm Example: 2523=253=22=22=4 

 

12m75n84p420m56n4=2(m7m5)(n8n4)p4=2m75n84p412m75n84p420m56n4=2m2n4p4

 Formula Product rule with same exponent: anbn=(ab)n Example: 3242=(34)2=122=1212=144

Thanks Heureka,

You have answered beautifully,

 

Just a little note.

Heureka's dots are multiply signs.  

 

Some people use dots instead of  of a x sign.     It is quite common in advanced mathematics.
