Question Evaluate the expression $2 \cdot(-1 \div 6)^{4}$ to find the equivalent value.

Studdy Solution

STEP 1

Assumptions
1. The expression to evaluate is $2 \cdot(-1 \div 6)^{4}$ .
2. The operations must be performed following the order of operations: parentheses, exponents, multiplication and division from left to right.

STEP 2

First, we need to evaluate the expression inside the parentheses.
$(-1 \div 6)$

STEP 3

Perform the division inside the parentheses.
$(-1 \div 6) = -\frac{1}{6}$

STEP 4

Next, we need to raise the result of the division to the power of 4 as indicated by the exponent.
$\left(-\frac{1}{6}\right)^{4}$

STEP 5

When raising a negative fraction to an even power, the result is positive. We will raise both the numerator and the denominator to the power of 4.
$\left(-\frac{1}{6}\right)^{4} = \left(-1\right)^{4} \cdot \left(\frac{1}{6}\right)^{4}$

STEP 6

Calculate the value of the negative one raised to the fourth power.
$\left(-1\right)^{4} = 1$

STEP 7

Calculate the value of one-sixth raised to the fourth power.
$\left(\frac{1}{6}\right)^{4} = \frac{1^4}{6^4}$

STEP 8

Simplify the fraction.
$\frac{1^4}{6^4} = \frac{1}{1296}$

STEP 9

Combine the results from steps 6 and 8.
$\left(-\frac{1}{6}\right)^{4} = 1 \cdot \frac{1}{1296} = \frac{1}{1296}$

STEP 10

Now, we need to multiply the result by 2 as indicated by the expression.
$2 \cdot \frac{1}{1296}$

STEP 11

Perform the multiplication.
$2 \cdot \frac{1}{1296} = \frac{2}{1296}$

STEP 12

Simplify the fraction by dividing both the numerator and the denominator by the greatest common divisor, which is 2.
$\frac{2}{1296} = \frac{1}{648}$

STEP 13

Convert the fraction to a decimal to match the answer choices.
$\frac{1}{648} \approx 0.00154320987654321$

STEP 14

Round the decimal to three significant figures to match the answer choices.
$0.00154320987654321 \approx 0.00154$

STEP 15

Now we compare the result with the answer choices. The closest value to our result is 0.002.
The value equivalent to the expression $2 \cdot(-1 \div 6)^{4}$ is 0.002, which corresponds to answer choice c.
