Introduction

In mathematics, identifying patterns and applying them to solve problems is a crucial skill. However, even with the right approach, mistakes can occur. In this article, we will analyze the steps taken by Tasha to find the value of $4^{-3}$ and determine where she made the first error.

Tasha's Steps

Tasha used the following steps to find the value of $4^{-3}$ :

Find a pattern in the table: Tasha noticed a pattern in the table where the previous value is divided by 4 when the exponent decreases by 1.
Apply the pattern: Tasha applied the pattern to find the value of $4^{-3}$ .

The First Error

Let's examine Tasha's steps more closely to identify where she made the first error.

Step 1: Finding a Pattern in the Table

Tasha correctly identified a pattern in the table where the previous value is divided by 4 when the exponent decreases by 1. This pattern is a common one in mathematics, where the value of a number raised to a negative power is equal to the reciprocal of the number raised to the positive power.

For example, $4^{-3} = \frac{1}{4^3}$ . However, Tasha's pattern is not entirely accurate. The pattern she described is more like a rule for finding the value of a number raised to a negative power, rather than a pattern in the table.

Step 2: Applying the Pattern

Tasha applied the pattern to find the value of $4^{-3}$ . However, she made a mistake in her calculation. She wrote $4^{-3} = \frac{1}{16}$ , which is incorrect.

The correct calculation for $4^{-3}$ is:

$4^{-3} = \frac{1}{4^3} = \frac{1}{64}$

Conclusion

In conclusion, Tasha made the first error in her calculation when she applied the pattern to find the value of $4^{-3}$ . She incorrectly wrote $4^{-3} = \frac{1}{16}$ , when the correct calculation is $4^{-3} = \frac{1}{64}$ .

Key Takeaways

Identifying patterns and applying them to solve problems is a crucial skill in mathematics.
However, even with the right approach, mistakes can occur.
It's essential to double-check calculations and verify the accuracy of the results.
