0.4 x 3 = 1.2

So your answer is 1.2

Answer 2

Answer: The required simplified value of the given expression is 0.064.

Step-by-step explanation: We are given to simplify the following expression :

`E=(0.4)^3~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)`

To find the required value, we need to convert the decimal to fraction and then take the third power of that.

The simplification of expression (i) is as follows :

`E\\\\\\=(0.4)^3\\\\\\=\left((4)/(10)\right)^3\\\\\\=(64)/(1000)\\\\=0.064.`

Thus, the required simplified value of the given expression is 0.064.
