Printable worksheet for practicing scientific notation conversion.

Let's solve each problem step by step and express each number in scientific notation.

🔹 What is Scientific Notation?

Scientific notation is a way of writing very large or very small numbers in the form:
$$
a \times 10^n
$$
where:
- $1 \leq a < 10$ (a number between 1 and 10),
- $n$ is an integer (positive or negative),
- The decimal point is moved so that only one non-zero digit is to the left of the decimal.

We’ll go through each number:

---

1) 562

Move the decimal point 2 places to the left:
562 → 5.62
So, $562 = 5.62 \times 10^2$

✔ Answer: $5.62 \times 10^2$

---

2) 4,216

Move decimal 3 places left:
4,216 → 4.216
So, $4,216 = 4.216 \times 10^3$

✔ Answer: $4.216 \times 10^3$

---

3) 49,603

Move decimal 4 places left:
49,603 → 4.9603
So, $49,603 = 4.9603 \times 10^4$

✔ Answer: $4.9603 \times 10^4$

---

4) 25

Move decimal 1 place left:
25 → 2.5
So, $25 = 2.5 \times 10^1$

✔ Answer: $2.5 \times 10^1$

---

5) 128,569

Move decimal 5 places left:
128,569 → 1.28569
So, $128,569 = 1.28569 \times 10^5$

✔ Answer: $1.28569 \times 10^5$

---

6) 836

Move decimal 2 places left:
836 → 8.36
So, $836 = 8.36 \times 10^2$

✔ Answer: $8.36 \times 10^2$

---

7) 9,364

Move decimal 3 places left:
9,364 → 9.364
So, $9,364 = 9.364 \times 10^3$

✔ Answer: $9.364 \times 10^3$

---

8) 34,121

Move decimal 4 places left:
34,121 → 3.4121
So, $34,121 = 3.4121 \times 10^4$

✔ Answer: $3.4121 \times 10^4$

---

9) 22

Move decimal 1 place left:
22 → 2.2
So, $22 = 2.2 \times 10^1$

✔ Answer: $2.2 \times 10^1$

---

10) 912

Move decimal 2 places left:
912 → 9.12
So, $912 = 9.12 \times 10^2$

✔ Answer: $9.12 \times 10^2$

---

11) 7,350

Move decimal 3 places left:
7,350 → 7.35
So, $7,350 = 7.35 \times 10^3$

✔ Answer: $7.35 \times 10^3$

---

12) 4,874

Move decimal 3 places left:
4,874 → 4.874
So, $4,874 = 4.874 \times 10^3$

✔ Answer: $4.874 \times 10^3$

---

13) 80,256

Move decimal 4 places left:
80,256 → 8.0256
So, $80,256 = 8.0256 \times 10^4$

✔ Answer: $8.0256 \times 10^4$

---

14) 13,058

Move decimal 4 places left:
13,058 → 1.3058
So, $13,058 = 1.3058 \times 10^4$

✔ Answer: $1.3058 \times 10^4$

---
