Which expression is a perfect cube?

Bingel [31]

we know that

A perfect cube is a whole number which is the cube of another whole number or a number is a perfect cube if the cube root of that number is a whole number.

case a) $12x^{12} y^{18}$

$12x^{12} y^{18} = 12(x^{4} y^{6})^{3}$

the cube root of $12$ is not a whole number

therefore

The expression is not a perfect cube

case b) $12x^{27} y^{125}$

$12x^{27} y^{125} = 12(x^{9})^{3}y^{125}$

the cube root of $12$ is not a whole number

the cube root of $y^{125}$ is not a whole number

therefore

The expression is not a perfect cube

case c) $64x^{15} y^{18}$

$64x^{15} y^{18} = (4 x^{5} y^{6})^{3}$

therefore

The expression is a perfect cube

case d) $64x^{27} y^{125}$

$64x^{27} y^{125} = (4 x^{9})^{3}y^{125}$

the cube root of $y^{125}$ is not a whole number

therefore

The expression is not a perfect cube

the answer is

$64x^{15} y^{18}$

What is 0.5, 1/5, 0.35, 12/25, and 4/5 from least to greatest

Margaret [11]

Change each into decimal

0.5 = 0.5

1/5 = 0.2

0.35 = 0.35

12/25 = 0.48

4/5 = 0.80

Set in order from least to greatest.

0.2, 0.35, 0.48, 0.5, 0.80

1/5, 0.35, 12/25, 0.5, 4/5 is your order.

hope this helps
