Question

Two fifths of the square of a number j algebraic exxpression

Answer 1

`(2)/(5)j^(2)`

Explanation:

• We have a number represented by the letter
  `j`.

• The question asks for two fifths
  `((2)/(5) )` of the square of this number.

1. To square a number means to multiply a number by itself. The result will be the number raised to the power of 2. Applying this to
   `j`, we get
   `j*j`
   `=j^2`
2. Two fifths of this term (
   `j^2`) is 
   `(2)/(5)j^(2)`. This is our final answer.
