what you do is simple ... you just use the ^ function ..
so the first one you do 810000 x 1.04^4 = 947585.4336
this is because it increases 4 percent per year..... so 1.04 ( because 1 =100 and 0.4 =4 percent) then because it is 4 years you use the ^ function with whatever question.. =)
second one:
10000 x 1.08^10 = 21589.2499727279
again this is because 1 = 100 percent and the 0.08 the 8 percent increase then because it is 10 years you do ^10 =)
hope it helped!
