What are Exponents?

---

Exponents are a shorthand way of expressing repeated multiplication of a number. In the expression $23.8 \times 10^2$, the exponent $2$ indicates that the number $10$ should be multiplied by itself $2$ times. This can be written as $10 \times 10$ or $10^2$.

The Importance of Exponents in Mathematics

---

Exponents are a fundamental concept in mathematics, and they play a crucial role in many mathematical operations. They allow us to express complex calculations in a simpler and more concise way. For example, the expression $10^2$ is equivalent to $100$, which is a much simpler way of expressing the result of multiplying $10$ by itself $2$ times.

How to Calculate Exponents

---

Calculating exponents is a straightforward process. To calculate the value of an exponent, you simply multiply the base number by itself as many times as indicated by the exponent. For example, to calculate the value of $10^2$, you would multiply $10$ by itself $2$ times, which gives you $100$.

Calculating the Value of $23.8 \times 10^2$

---

To calculate the value of $23.8 \times 10^2$, we need to multiply $23.8$ by the result of $10^2$. As we discussed earlier, $10^2$ is equivalent to $100$. Therefore, we can rewrite the expression as $23.8 \times 100$.

Multiplying $23.8$ by $100$

---

To multiply $23.8$ by $100$, we need to multiply the decimal part of the number by $100$ and then add the result to the product of the whole number part and $100$. In this case, the decimal part of the number is $0.8$, and the whole number part is $23$.

Calculating the Product of $23.8$ and $100$

---

To calculate the product of $23.8$ and $100$, we can use the following steps:

1. Multiply the decimal part of the number ($0.8$) by $100$: $0.8 \times 100 = 80$
2. Multiply the whole number part of the number ($23$) by $100$: $23 \times 100 = 2300$
3. Add the results of steps 1 and 2: $80 + 2300 = 2380$

The Final Answer

---

Therefore, the value of $23.8 \times 10^2$ is $2380$.
