6⋅2x for the given values of

x:Answer:

Step-by-step explanation:

(a) For

=

−

2

x=−2:

6

⋅

2

=

6

⋅

2

(

−

2

)

6⋅2x=6⋅2(−2)

Calculate inside the parentheses first:

6

⋅

2

(

)

=

6

⋅

(

−

4

)

6⋅2(−2)=6⋅(−4)

Now, perform the multiplication:

6

⋅

(

−

)

=

−

24

6⋅(−4)=−24

So,

6

⋅

6⋅2x when

=

.

(b) For

)

6⋅2x=6⋅2(3)

Calculate inside the parentheses first:

6

⋅

)

=

6

⋅

6

6⋅2(3)=6⋅6

Now, perform the multiplication:

6

⋅

6

=

36

6⋅6=36

So,

6

⋅

2

6⋅2x when

=

.

Therefore, the evaluated expressions are
