Answer:
The number 221,436 in scientific notation is 2.21436 x 10⁵.
Step-by-step explanation:
Scientific notation is a way of expressing numbers that are too large or too small to be conveniently written in decimal form. These numbers must be between 1-10
- => 221,436 = 22,143.6 x 10¹
This number is too large. The number must be between 1 and 10.
- => 22,143 x 10¹ = 2,214.36 x 10²
This number is too large. The number must be between 1 and 10.
- 2,214.36 x 10² = 221.436 x 10³
This number is too large. The number must be between 1 and 10.
- 221.436 x 10³ = 22.1436 x 10⁴
This number is too large. The number must be between 1 and 10.
- 22.1436 x 10⁴ = 2.21436 x 10⁵
This number is perfect. It is between 1 and 10.
Hence, the number 221,436 in scientific notation is 2.21436 x 10⁵.
