Math Problem Statement

An expression is shown: (x^6)^10 / (w^2x^2y^12) * w^6y^6 where w ≠ 0, x ≠ 0, and y ≠ 0. Select all of the expressions that are equivalent to the given expression.

Solution

Let's first simplify the given expression step by step:

The original expression is:

(x6)10w6y6w2x2y12\frac{(x^6)^{10} \cdot w^6 y^6}{w^2 x^2 y^{12}}

Step 1: Simplify each part of the expression

  • (x6)10=x60(x^6)^{10} = x^{60}
  • The numerator becomes x60w6y6x^{60} \cdot w^6 \cdot y^6.
  • The denominator remains w2x2y12w^2 x^2 y^{12}.

So now the expression looks like:

x60w6y6w2x2y12\frac{x^{60} \cdot w^6 \cdot y^6}{w^2 \cdot x^2 \cdot y^{12}}

Step 2: Apply the laws of exponents

  • For xx, x60÷x2=x602=x58x^{60} \div x^2 = x^{60 - 2} = x^{58},
  • For ww, w6÷w2=w62=w4w^6 \div w^2 = w^{6 - 2} = w^4,
  • For yy, y6÷y12=y612=y6y^6 \div y^{12} = y^{6 - 12} = y^{-6}.

So the simplified expression becomes:

x58w4y6x^{58} \cdot w^4 \cdot y^{-6}

This is the final simplified form of the given expression.

Now let's check which of the provided expressions match this simplified form:

  1. (x6)5w3y2\frac{(x^6)^5}{w^3 y^2}:
    Simplifies to x30w3y2\frac{x^{30}}{w^3 y^2}, which is not equivalent.

  2. x30w3y2\frac{x^{30}}{w^3 y^2}:
    This is already in simplified form, which is not equivalent.

  3. w4x58y6\frac{w^4 x^{58}}{y^6}:
    Simplifies to x58w4y6x^{58} \cdot w^4 \cdot y^{-6}, which is equivalent.

  4. x14y6w4\frac{x^{14}}{y^6} \cdot w^4:
    Simplifies to x14w4y6x^{14} \cdot w^4 \cdot y^{-6}, which is not equivalent.

  5. (w2x7y3)2\left( w^2 x^7 y^3 \right)^2:
    Simplifies to w4x14y6w^4 \cdot x^{14} \cdot y^6, which is not equivalent.

  6. (w2x29y3)2\left( w^2 x^{29} y^3 \right)^2:
    Simplifies to w4x58y6w^4 \cdot x^{58} \cdot y^6, which is not equivalent.

  7. (x3)10w4y2(x^3)^{10} \cdot w^4 y^{-2}:
    Simplifies to x30w4y2x^{30} \cdot w^4 \cdot y^{-2}, which is not equivalent.

Conclusion:

The correct expression that matches the simplified form is w4x58y6\frac{w^4 x^{58}}{y^6}.
