Answer:

9.74418019cm=h

~ 9.7442

Step-by-step explanation:

volume of a cylinder=πr²h

radius=½of diameter

=½×140cm

=70cm

1l=1000cm³

150l=150l/1l×1000cm³

=150000cm³

150000cm³=π(70cm)²×h

150000cm³=15393.8040cm²h

150000cm³/15393.8040cm²=15393.8040cm²h/15393.8040cm²

150000cm³/15393.8040cm²=h

9.74418019cm=h

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:

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