Question

ormula">÷$1000^{n}$ can ne written in the form $10^{z}$
Express z in terms of m and n

Answer 1

Answer:

Step-by-step explanation:

hello :

100^m / 1000^n

look : 100 = 10²  and 1000 = 10^3

so : 100^m = (10²)^m= 10^2m      and   1000^n = ( 10^3)^n = 10^3n

100^m / 1000^n = 10^2m / 10^3n

conclusion : 100^m / 1000^n =  (10^(2m-3n))   when : z = 2m-3n
