Answer:
The answer is option 2, by simplifying 9 to 3² to make both powers base 3 and subtracting the exponents.
Step-by-step explanation:
You have to make the expressions into the same base :

Next, you have to apply Indices Law :




Answer:
5b(2 - 5b²)
Step-by-step explanation:
Simply take out GCFs to factor out the expression:
Step 1: Factor out GCF of 5
5(2b - 5b³)
Step 2: Factor out GCF of <em>b</em>
5b(2 - 5b²)
We can't factor the quadratic any further so that is our final answer.
5 times 2 plus .015 times 2
∠DOC is the average of the given angle values,
(170° +44°)/2 = 107°
∠DOB is the supplement to that,
180° -107° = 73°
The appropriate choice is
B) 73°
