Answer:
Step-by-step explanation:
We first let 0.38 (8 being repeated) be T.
Since z is recurring in 1 decimal places, we multiply it by 10. 10z = 3.88
Next, we subtract them. 10 r T 3.88 0.38 9x 3.5
Lastly, we divide both sides by 9 to get IC as a fraction. 3.5 T 9 35 90 7 18
If i= V-1, then -117 expression is equal to 9i(13i)
Step-by-step explanation:
Original problem : 9i(13i)
=> 117 (Multiply)
=> 117 * -1
=> = -1
=> -117
If i= V-1, then -117 expression is equal to 9i(13i)
