Write 7 1/5 in radical form
dybincka [34]
<h2>The simplest form of radical 7^{\dfrac{1}{5}} = \sqrt[5]{7} .</h2>

Step-by-step explanation:

We have,

7^{\dfrac{1}{5}}

To find, the radical form of 7^{\dfrac{1}{5}} = ?

∴ 7^{\dfrac{1}{5}}

We know that,

Any number raised to the power of reciprocal n is the  n^{th}  root of that number.

= \sqrt[5]{7}

∴ 7^{\dfrac{1}{5}} = \sqrt[5]{7} [ ∵ 7 is a prime number,  the simplest form of radical]

Thus, the simplest form of radical 7^{\dfrac{1}{5}} = \sqrt[5]{7} .

Which problem can be solved by expression 3/8 divided 1/4?
NeTakaya

Answer:

3/8÷1/4=1 1/2

Step-by-step explanation:

I am not sure what you are asking here, So I am gonna explain how you divide this.

So using the KCF method (Keep Change Flip) You would KEEP the first fraction (3/8) and CHANGE the operation (from divide to multiply) then FLIP your second fraction (1/4 to 4/1)

After doing this, it should look like:

3 4

x

8 1

Now that we got that, you multiply from left to right. 3×4 is 12. 8×1=8.

That should leave you with 12/8. But this is an improper fraction. So you would divide top by bottom to get a mixed fraction.

It should look like this

01. 1 1/2

8 12

8

4

Step by step explanation:

8 only goes into 12 one time. So you would subtract 12 by 8, and get 4. From that you would get 1 4/8 but 1 4/8 can be simplified to 1 1/2.

So it is 1 1/2
