The simplest form of (64/729) ^-1/6 is -2/33/24/33/4 The Correct Answer and Explanation is: To simplify the expression: (64729)−16\left(\frac{64}{729}\right)^{-\frac{1}{6}} ✅ Step 1: Apply the negative exponent rule a−n=1ana^{-n} = \frac{1}{a^n} So: (64729)−16=(72964)16\left(\frac{64}{729}\right)^{-\frac{1}{6}} = \left(\frac{729}{64}\right)^{\frac{1}{6}} ✅ Step 2: Prime factorization of 729 and 64 So: (72964)16=(3626)16=36×1626×16=32\left(\frac{729}{64}\right)^{\frac{1}{6}} = \left(\frac{3^6}{2^6}\right)^{\frac{1}{6}} = \frac{3^{6 \times \frac{1}{6}}}{2^{6 \times \frac{1}{6}}} = \frac{3}{2}

Let’s follow the steps carefully. Step 1: Simplify the

What is the following product?\n()()\n\n\n\n The Correct Answer and Explanation is: We are asked to simplify the product: (12+6)(6−10)(\sqrt{12} + \sqrt{6})(\sqrt{6} – \sqrt{10}) Step 1: Simplify Square Roots Let’s simplify any square roots where possible: So the expression becomes: (23+6)(6−10)(2\sqrt{3} + \sqrt{6})(\sqrt{6} – \sqrt{10}) Step 2: Use FOIL (Distributive Property) Apply the distributive property (FOIL):

Buffers. Calculate the pH of a buffer solution prepared by dissolving 0.20 mole of cyanic acid (HCNO) and 0.80 mole of sodium cyanate (NaCNO) in enough water to make 1.0 liter of solution. [Ka(HCNO) = 2.0 × 10–4] The Correct Answer and Explanation is: To calculate the pH of a buffer solution composed of a
