Understanding Exponential Equations

Exponential equations are mathematical expressions that involve a base number raised to a power, often denoted by an exponent. In the given equation, $5.6 \times 10^{\square} = 56,000$ , we are asked to find the missing exponent. To solve this problem, we need to understand the concept of exponential equations and how to manipulate them to isolate the exponent.

The Basics of Exponential Equations

Exponential equations are written in the form $a^b = c$ , where $a$ is the base, $b$ is the exponent, and $c$ is the result. In the given equation, $5.6 \times 10^{\square} = 56,000$ , the base is $5.6$ and the exponent is the missing value we need to find. The result is $56,000$ .

Converting to Scientific Notation

To solve this problem, we need to convert the result, $56,000$ , to scientific notation. Scientific notation is a way of expressing numbers in the form $a \times 10^b$ , where $a$ is a number between $1$ and $10$ and $b$ is an integer. To convert $56,000$ to scientific notation, we can divide it by $10,000$ , which gives us $5.6 \times 10^4$ .

Comparing the Two Expressions

Now that we have converted the result to scientific notation, we can compare it to the original equation. We have $5.6 \times 10^{\square} = 56,000$ , which is equivalent to $5.6 \times 10^4$ . This means that the missing exponent is $4$ .

Conclusion

In conclusion, the missing exponent in the equation $5.6 \times 10^{\square} = 56,000$ is $4$ . This can be found by converting the result to scientific notation and comparing it to the original equation.
