Question

If x = 0.008, find x raised to -1/3

Answer 1

Answer:

x=8/1000

x=(2/10)^3

(x)^-1/3=(2/10)^3*-1/3

=(2/10)^-1

=(1/5)^-1

=5

Answer 2

Answer:

0.25^1 =0.25 = \frac{1}{4}

Step-by-step explanation:

Given : (\frac{1}{5})^{3y}=0.008

To Find : the value of 0.25^y

Solution:

(\frac{1}{5})^{3y}=0.008

(0.2)^{3y}=0.008

(0.2^3)^y=(0.2)^3

0.2^y=(0.2)

On comparing y = 1

Now to find the value of 0.25^y

Substitute y = 1

So, 0.25^1 =0.25=¼

Therefore,

the answer is ¼
