I am not sure what does that question mean by simplify. If it means not to solve and just arrange;
You can divide the whole of the equation to m^2
Then you get;
19/m -4 +4
And you can divide the whole equation to 4 then you get;
19/4m -1 +1
You can also write as ;
(1/m * 19/4) - 1 + 1
C. Not similar hope this helps
The answer is 66.
66 * 3 = 198
66 * 5 = 330
Answer:
Step-by-step explanation:
=7 (1+11+111+1111......n)
=7/9 (9+99+999+9999....n)
=7/9 ((10-1)+(10^2-1)+(10^3-1)+....n)
=7/9 ((10+10^2+10^3...n)-(1+1+1+1.....n))
=7/9 ((10 (10^n-1)/(10-1))-n)
