Vladimir [108]

Given:

The expression is

$\sqrt{\sqrt[3]{6}}$

To find:

The simplified form of the given expression.

Solution:

We have,

$\sqrt{\sqrt[3]{6}}$

Using the properties of radical and exponent, we get

$=(\sqrt[3]{6})^{\frac{1}{2}}$ $[\because \sqrt{x}=x^{\frac{1}{2}}]$

$=\left(6^{\frac{1}{3}}\right)^{\frac{1}{2}}$ $[\because \sqrt[n]{x}=x^{\frac{1}{n}}]$

$=6^{\frac{1}{3}\times\frac{1}{2}}$ $[\because (a^m)^n=a^{mn}]$

$=6^{\frac{1}{6}}$

Therefore, the correct option is A.

In 2002 there was estimated to be 6Billon people on earth. 20 percent of people lived on less than a 1$ a day. How many people l

kykrilka [37]

Hiya!

So, 6 billion is 100%. 50% is 3 billion. 25% is 1.5 billion. 20% must be 1.2 billion because 1.2 × 5 is 6. I know that 20% is 1/5 of 100%, and that's how I got my answer.

If you found this especially helpful, I'd appreciate if you'd vote me Brainliest for your answer, if other people did not provide a helpful answer (but, I'm sure they did!). I want to be able to assist more users one-on-one! :)

A square sheet of paper measures 25 centimeters on each side. What is the length of the diagonal of this paper?

Varvara68 [4.7K]

Answer:

35.36 cm

Step-by-step explanation:

The diagonal of a square will be given by

$D=\sqrt {a^{2}+b^{2}}$

Where a is the length of one side and b is the length of another side. For a square, botj sides are equal hence the diagonal calculations will be as follows

Given that a is 25 then

$D=\sqrt {25^{2}+25^{2}}$

D=35.3553390593274

Rounding off the nearest two decimal place

D=35.36 cm
