The exponent for that would be 13^3.
If the answer is incorrect, then i am sorry.
15+70+45=130 :)) that’s how u calculate the perimeter just add them all together.
Answer:
a.
= 
b. 
Step-by-step explanation:
a) When <em>n </em>is even, then it is divisible by 2. Because of this, you can write:
b) When <em>n </em>is odd, then <em>n - 1 </em> is even. This would make it divisible by 2, and there would be a remainder of 1, so we can write:
×
