Simplify the radical expression 4 square root 81x^20y^8

Dimas [21]

The simplified expression is $3x^5 y^2$

Step-by-step explanation:

The radical expression to simplify is

$\sqrt[4]{81x^{20}y^8}$

We notice the following:

$81=3^4$

And using the property

$(x^a)^b=x^{a\cdot b}$

we can write:

$x^{20}=(x^5)^4$

$y^8 = (y^2)^4$

So the argument of the radical can be written as

$\sqrt[4]{(3)^4(x^5)^4(y^2)^4} =\sqrt[4]{(3x^5y^2)^4}$

And now by using the property

$\sqrt[n]{a^n}=a$

We find:

$\sqrt[4]{(3x^5y^2)^4}=3x^5 y^2$

-5/8(-3/8 minus one fourth)

Ne4ueva [31]

The value of $\frac{-5}{8} (\frac{-3}{8}-\frac{1}{4} )$ = 25/64

<h3>What is fraction?</h3>

A fraction simply tells us how many parts of a whole we have. You can recognize a fraction by the slash that is written between the two numbers.

$\frac{-5}{8} (\frac{-3}{8}-\frac{1}{4} )$

= -5/8 (-3/8 -2/8)

= -5/8 (-5/8)

= 25/64

Thus, $\frac{-5}{8} (\frac{-3}{8}-\frac{1}{4} )$ = 25/64
