Math Problem Statement

Solve the equation: 4^(√3/2) * (1/8)^(√27) = (16^(5√3))^-2

Solution

The expression provided in the image is:

432(18)27=(1635)24^{\frac{\sqrt{3}}{2}} \cdot \left( \frac{1}{8} \right)^{\sqrt{27}} = \left(16^{\sqrt[5]{3}}\right)^{-2}

Let's solve this step-by-step.

Step 1: Simplify the Left-Hand Side

The left-hand side of the equation is:

432(18)274^{\frac{\sqrt{3}}{2}} \cdot \left( \frac{1}{8} \right)^{\sqrt{27}}

We can rewrite each term using exponents:

  1. 432=(22)32=2232=234^{\frac{\sqrt{3}}{2}} = (2^2)^{\frac{\sqrt{3}}{2}} = 2^{2 \cdot \frac{\sqrt{3}}{2}} = 2^{\sqrt{3}}

  2. (18)27=(81)27=827\left(\frac{1}{8}\right)^{\sqrt{27}} = \left(8^{-1}\right)^{\sqrt{27}} = 8^{-\sqrt{27}}

Since 8=238 = 2^3, we can rewrite it as:

827=(23)27=23278^{-\sqrt{27}} = (2^3)^{-\sqrt{27}} = 2^{-3\sqrt{27}}

Therefore, the left-hand side becomes:

232327=233272^{\sqrt{3}} \cdot 2^{-3\sqrt{27}} = 2^{\sqrt{3} - 3\sqrt{27}}

Step 2: Simplify the Right-Hand Side

The right-hand side of the equation is:

(1635)2\left(16^{\sqrt[5]{3}}\right)^{-2}

We know 16=2416 = 2^4, so:

[ 16^{\sqrt[5]{3}} = (2^4)^{\sqrt[5]{3}} = 2^{4\sqrt[5]{3}} ]

Raising it to the power of 2-2:

[ \left(2^{4\sqrt[5]{3}}\right)^{-2} = 2^{-8\sqrt[5]{3}} ]

Step 3: Equating the Exponents

Now, we equate the exponents from both sides:

3327=835\sqrt{3} - 3\sqrt{27} = -8\sqrt[5]{3}

Step 4: Solving for the Expression

To solve this equation, we need to simplify further:

  • Recall that 27=33=33\sqrt{27} = \sqrt{3^3} = 3\sqrt{3}.
  • Also, 35\sqrt[5]{3} remains as is.

So, substituting these into the equation:

33(33)=835\sqrt{3} - 3(3\sqrt{3}) = -8\sqrt[5]{3}

This simplifies to:

393=835\sqrt{3} - 9\sqrt{3} = -8\sqrt[5]{3}

83=835-8\sqrt{3} = -8\sqrt[5]{3}

Divide both sides by 8-8:

3=35\sqrt{3} = \sqrt[5]{3}

Conclusion

The equation holds true when 3=35\sqrt{3} = \sqrt[5]{3}. This is a unique scenario where both sides are equal.
