Understanding the Problem

In this problem, we are asked to evaluate the cube root of 0.008. The cube root of a number is a value that, when multiplied by itself three times, gives the original number. In mathematical notation, this is represented as 3x{}^3 \sqrt{x}, where xx is the number inside the cube root.

The Formula for Cube Root

The formula for the cube root of a number is:

3x=x3{}^3 \sqrt{x} = \sqrt[3]{x}

This formula tells us that to find the cube root of a number, we need to raise that number to the power of 13\frac{1}{3}.

Evaluating the Cube Root of 0.008

Now that we understand the formula for the cube root, let's apply it to the number 0.008.

30.008=0.0083{}^3 \sqrt{0.008} = \sqrt[3]{0.008}

To evaluate this expression, we need to raise 0.008 to the power of 13\frac{1}{3}.

Raising a Decimal Number to a Power

When we raise a decimal number to a power, we need to follow the rules of exponentiation. In this case, we need to raise 0.008 to the power of 13\frac{1}{3}.

To do this, we can use the fact that 0.008=8×1030.008 = 8 \times 10^{-3}. Then, we can raise this expression to the power of 13\frac{1}{3}.

30.008=8×1033{}^3 \sqrt{0.008} = \sqrt[3]{8 \times 10^{-3}}

Using the properties of exponents, we can rewrite this expression as:

30.008=(8×103)13{}^3 \sqrt{0.008} = (8 \times 10^{-3})^{\frac{1}{3}}

Simplifying the Expression

Now that we have raised 0.008 to the power of 13\frac{1}{3}, we can simplify the expression.

(8×103)13=2×101(8 \times 10^{-3})^{\frac{1}{3}} = 2 \times 10^{-1}

Evaluating the Expression

Finally, we can evaluate the expression by multiplying 2 by 10110^{-1}.

2×101=0.22 \times 10^{-1} = 0.2

Conclusion

In conclusion, the cube root of 0.008 is 0.2.

Answer

The correct answer is:

  • d. 0.2
