Answer:
8.84 ×10⁻¹
Step-by-step explanation:
Move one decimal to the right to make one number go after the decimal. (ONLY one number from 0 - 9)
0.884 to 08.84
Now with how many times the decimal moves, it determines the power. Left equals positive and right is negative.
Standard form goes with × 10ˣ
the x next to 10 is the power.
The decimal moved 1 right so the power would be -1.
So,
8.84 × 10⁻¹
(-8x)+x+(-2x)
-7x+(-2x)
-9x
