Answer: 5(1,215x)^{\frac{1}{2}}

Step-by-step explanation:}

To solve this problem you can apply the proccedure shown below:

1. By definition, you have that:

\sqrt[n]{a}=a^{{\frac{1}{n}}

2. Therefore, keeping the above on mind, you can find an equivalent expression of 5\sqrt{1,215x} as following:

5\sqrt{1,215x}=5(1,215x)^{\frac{1}{2}}

3. Then, an equivalent expression is:

5(1,215x)^{\frac{1}{2}}

Answer with explanation

The expression whose equivalent expression we have to find is:

  \Rightarrow 5 \sqrt{1215 x}\\\\\text{Following are the equivalent expression}\\\\1.\rightarrow 5 \sqrt{243 \times 5\times x}\\\\2.\rightarrow 5 \times\sqrt{3\times 3\times 3\times 3\times 3\times 5 \times x}\\\\3.\rightarrow 5 \times 3\times 3 \times \sqrt{15 x}\\\\ 4.\rightarrow 45 \sqrt{15 x}\\\\5. \rightarrow 45 \times (15)^{\frac{1}{2}} \times x^{\frac{1}{2}

Option 2: 4^{\frac{1}{6}} is the correct answer.

Step-by-step explanation:

The radical expressions like these are simplified by using fractional exponents

given

\frac{\sqrt{4}}{\sqrt[3]{4} }

Converting radicals into exponents

When there is no base the exponent is 1/2 and as the base is 3, the exponent will be 1/3

So

=\frac{4^{\frac{1}{2}}}{4^{\frac{1}{3}}}

As the bases of numerator and denominator is same, the exponents can be subtracted

=4^{\frac{1}{2}-\frac{1}{3}}\\=4^{\frac{3-2}{6}}\\=4^{\frac{1}{6}}

Hence,

Option 2: 4^{\frac{1}{6}} is the correct answer.

Multi step equations
miv72 [106K]

-86 = -6(-3p - 3) - 5p

Distribute the -6 into the parentheses:

-86 = (-6 * -3p) + (-6 * -3) - 5p

-86 = 18p + 18 - 5p

Simplify:

-86 = 13p + 18

Subtract both sides by 18:

-86 - 18 = 13p + 18 - 18

-104 = 13p

Divide both sides by 13:

\frac{13p}{13} = \frac{-104}{13}

\frac{p}{1} = \frac{-8}{1}

<u>p = -8</u>

<u></u>

Good luck! If you have any questions, don't be afraid to ask :))

If f(x) = 2x2 5x, find f(3b).
frez [133]
F(x) = 2x^2 + 5x
f(3b) = 2(3b)^2 + 5(3b) = 2(9b^2) + 15b = 18b^2 + 15b

A supplier delivers an order for 20 electric toothbrushes to a store. by accident, three of the electric toothbrushes are defect
evablogger [386]
<span>3 of the 20 toothbrushes are defective, so the initial probability of selecting a defective toothbrush on the first try is 3/20. After that, there will be 2 defective toothbrushes in the remaining 19, so the probability of selecting one of those on the 2nd try will be 2/19. To get the probability of those two events happening sequentially, we multiply the two probabilities. Thus (3/20)*(2/19) = 6/380 = 0.0157, or about 1.6%.</span>
