12*10^5 = 12*100000 = 1200000 ;
1200000 - 1000000 = 200000 ;
1.2*10^6 = 1.2*1000000 = 1200000;
1200000 - 1000000 = 200000;
Because 2000000 = 200000, neither of the two numbers is closer to 1 milion !
So what you would do in this equation is since it is 10 pennies in each stack and she has 50 stacks all you have to do 10 times 50 which equals 500 and since there are 100 pennies in a dollar you divide 500 by 100 which would get you five.
Answer:
Five dollars
And 500 pennies
X^2=169
x=√169
x=±13
