Math Problem Statement

Simplify the mathematical expression provided in the image.

Solution

The expression in the image can be interpreted as:

(227×875448)35\left( \frac{2\sqrt{27} \times 8\sqrt{75}}{4\sqrt{48}} \right)^{\frac{\sqrt{3}}{5}}

Let's break it down step by step:

Step 1: Simplifying the square roots

  • 27=9×3=33\sqrt{27} = \sqrt{9 \times 3} = 3\sqrt{3}
  • 75=25×3=53\sqrt{75} = \sqrt{25 \times 3} = 5\sqrt{3}
  • 48=16×3=43\sqrt{48} = \sqrt{16 \times 3} = 4\sqrt{3}

Step 2: Substituting these simplified terms back into the expression:

(2(33)×8(53)4(43))35\left( \frac{2(3\sqrt{3}) \times 8(5\sqrt{3})}{4(4\sqrt{3})} \right)^{\frac{\sqrt{3}}{5}}

Step 3: Simplifying the products:

  • Numerator: 2×33×8×53=240(3)2=240×3=7202 \times 3\sqrt{3} \times 8 \times 5\sqrt{3} = 240(\sqrt{3})^2 = 240 \times 3 = 720
  • Denominator: 4×43=1634 \times 4\sqrt{3} = 16\sqrt{3}

So, the expression becomes: (720163)35=(4513)35=(453)35\left( \frac{720}{16\sqrt{3}} \right)^{\frac{\sqrt{3}}{5}} = \left( 45\frac{1}{\sqrt{3}} \right)^{\frac{\sqrt{3}}{5}} = \left( \frac{45}{\sqrt{3}} \right)^{\frac{\sqrt{3}}{5}}

Step 4: Rationalizing the denominator:

Multiply the numerator and denominator by 3\sqrt{3} to rationalize the denominator: 4533=153\frac{45\sqrt{3}}{3} = 15\sqrt{3}

So the expression becomes: (153)35\left( 15\sqrt{3} \right)^{\frac{\sqrt{3}}{5}}

This is the simplified expression raised to the power of 35\frac{\sqrt{3}}{5}.
