wait not the discription srry
(99/9) + sqrt(9) = 14
9 + (9/9) = 10(99/9) - (9/9) = 10
10 times
1*10**-9s
One way: 99/9 - 9/9
9+(9*9+9)/(9+9)
The GCF of 9s and 63s^3 is 9s.
999 + (999/999) = 1000
(99)/(99) +9.
I'm not quite sure if this is what you mean but: 9/9=1 9+1=10 9/9=1 10*1=10 The whole thing: (9/9)*(9+(9/9))=10
1 ns (nanosecond) = 10-9s 1s / 10-9s = 109 109 = 1000 000 000 1 second = 1000 000 000 ns (nanosecond)
