Answer:
<u>After evaluating the expression, the result is 2/3</u>
Step-by-step explanation:
Let's evaluate the expression given to us:
-2 + 12 - 2³/ 2⁰ * 3
-2 + 12 - 8/ 1 * 3 ⇒ 2⁰ = 1 and 2³ = 8
-10 + 12/ 3
2/3
<u>After evaluating the expression, the result is 2/3</u>
The answer is 5b²/6c
Ok so you just have to simplify
15/18 = 5/6 (cause 3*5=15 and 3*6=18)
Then you do as the picture above says.
