1*10**-9s
1*10**-9s or 1 ns = 1E-9 s
10 times
9 + (9/9) = 10
9 + (9/9) = 10(99/9) - (9/9) = 10
The two ways are 8.517 and 8.516999... (9s repeating).
The GCF of 9s and 63s^3 is 9s.
1 ns (nanosecond) = 10-9s 1s / 10-9s = 109 109 = 1000 000 000 1 second = 1000 000 000 ns (nanosecond)
You could have one No. 9 or a handful of No. 9s
9÷9+99 or 99+9÷(9)
9s + 7 = -11 9s = -18 s = -18/9 s = -2
The GCF is 9s.
