Evaluate (5)8x
When x=-3

-120

Step-by-step explanation:

(5)8x

(5)(8)(-3)

5(-24)

= -120

Hi! I'm happy to help!

To solve this, we just have to insert -3 for x. Because the 5 in parenthesis is next to the eight with no other sign, it represents multiplication. Since the eight is next to the x with no other sign, it also means multiplication.

(5)8x

(5)·8·x

We can remove the parenthesis.

5·8·x

5·8·-3

40·-3

-120

So, when x=-3, (5)8x evaluates to -120.

I hope this was helpful, keep learning! :D
