Answer:

4x^5\sqrt[3]{3x}

Step-by-step explanation:

Given

\sqrt[3]{16x^7}\left(\sqrt[3]{12x^9}\right)\\\sqrt[3]{4^{2} x^7}\sqrt[3]{4(3)x^9}\\  4^\frac{2}{3} . x^\frac{7}{3} . 4^\frac{1}{3} . 3^\frac{1}{3} . x^\frac{9}{3}\\  4^\frac{2+1}{3} .  3^\frac{1}{3}. x^\frac{9+7}{3} \\4^\frac{3}{3} . 3^\frac{1}{3}. x^\frac{16}{3}\\ 4\sqrt[3]{3x^16}

4\sqrt[3]{3} . x^\frac{16}{3} \\4\sqrt[3]{3} . x^\frac{15}{3} .x^\frac{1}{3} \\4\sqrt[3]{3} . x^5 .x^\frac{1}{3} \\4x^5\sqrt[3]{3x} !

Answer:

The expression \sqrt[3]{16x^{7} }  * \sqrt[3]{12x^{9} } = 4x^{5}} (\sqrt[3]{3x})

Step-by-step explanation:

Given

\sqrt[3]{16x^{7} }  * \sqrt[3]{12x^{9} }

Required

Products of both

To do this, we have to apply the laws of indices,

Follow the highlighted steps

Step 1: Multiply both parameters directly

Since they both have the same roots, they can be multiplied directly according to the law of indices

\sqrt[3]{16x^{7} }  * \sqrt[3]{12x^{9} } becomes

\sqrt[3]{16x^{7} * 12x^{9} }

Step 2: Apply the 1st law of indices

First law of indices states that

x^{a} * x^{b} = x^{a + b}

So, \sqrt[3]{16x^{7} * 12x^{9} } becomes

\sqrt[3]{16x^{7} * 12x^{9} } = \sqrt[3]{16 * 12 * x^{7} * x^{9} }

\sqrt[3]{16x^{7} * 12x^{9} } = \sqrt[3]{16 * 12 * x^{7+9} }

\sqrt[3]{16x^{7} * 12x^{9} } = \sqrt[3]{16 * 12 * x^{16} }

\sqrt[3]{16x^{7} * 12x^{9} } = \sqrt[3]{192 * x^{16} }

Step 3: Rewrite the expression

\sqrt[3]{192 * x^{16} } = ({192 * x^{16} })^{\frac{1}{3} }

Step 4: Expand the Expression in bracket

({192 * x^{16} })^{\frac{1}{3} } = ({64 * 3*  x^{15} * x^{1} })^{\frac{1}{3} }

Break down into bits

({192 * x^{16} })^{\frac{1}{3} } = 64^\frac{1}{3} * 3^\frac{1}{3} *  (x^{15})^\frac{1}{3} * (x^{1})\frac{1}{3}

({192 * x^{16} })^{\frac{1}{3} } = (4^{3}) ^\frac{1}{3} * 3^\frac{1}{3} *  (x^{15})^\frac{1}{3} * (x^{1})\frac{1}{3}

({192 * x^{16} })^{\frac{1}{3} } = (4^{3*\frac{1}{3}}) * 3^\frac{1}{3} *  (x^{15}*^\frac{1}{3}) * (x^{\frac{1}{3}})

({192 * x^{16} })^{\frac{1}{3} } = 4 * 3^\frac{1}{3} *  (x^{5}}) * (x^{\frac{1}{3}})

({192 * x^{16} })^{\frac{1}{3} } = 4 (x^{5}})* 3^\frac{1}{3} *  (x^{\frac{1}{3}})

({192 * x^{16} })^{\frac{1}{3} } = 4x^{5}} * (3^\frac{1}{3} * x^{\frac{1}{3}})

({192 * x^{16} })^{\frac{1}{3} } = 4x^{5}} * (3x)^\frac{1}{3}

({192 * x^{16} })^{\frac{1}{3} } = 4x^{5}} * \sqrt[3]{3x}

({192 * x^{16} })^{\frac{1}{3} } = 4x^{5}} (\sqrt[3]{3x})

Hence, the expression \sqrt[3]{16x^{7} }  * \sqrt[3]{12x^{9} } = 4x^{5}} (\sqrt[3]{3x})

Diano4ka-milaya [45]

Answer:  (C) 0.1591

Step-by-step explanation:

Given : A manufacturer of radial tires for automobiles has extensive data to support the fact that the lifetime of their tires follows a normal distribution with

\mu=42,100\text{ miles}

\sigma=2,510\text{ miles}

Let x be the random variable that represents the lifetime of the tires .

z-score : z=\dfrac{x-\mu}{\sigma}

For x= 44,500 miles

z=\dfrac{44500-42100}{2510}\approx0.96

For x= 48,000 miles

z=\dfrac{48000-42100}{2510}\approx2.35

Using the standard normal distribution table , we have

The p-value : P(44500

P(z

Hence, the probability that a randomly selected tire will have a lifetime of between 44,500 miles and 48,000 miles =  0.1591
