The expression is n2.

Substitute n = 7 in the expression.

                                             (Substitute n = 7)

Base is 7 and exponent is 2.

 means 7 multiplied together 2 times.

                                 (Multiply: )

Substitute n = 0.4 in the expression.

                                       (Substitute n = 0.4)

Base is 0.4 and exponent is 2.

(0.4)2 means 0.4 multiplied together 2 times.

                        (Multiply: )

When n = 7 the solution is 49.

When n = 0.4 the solution is 0.16.
