<h3>How to understand power properties</h3>
Herein we must explain some properties of power expressions with integer exponents. A power of the form aᵇ is a product of the form a × a × a × a × ... × a, where a is repeated b times. a and b are the base and the exponent of the power.
First, we proceed to demonstrate that a⁰ = a:
a⁰ Given
a¹ ⁻ ¹ Existence of the additive inverse / Modulative property
a¹ · a⁻¹ Multiplication of powers of equal base
a¹ · (a¹)⁻¹ Power of a power / (- a) · b = - a · b
1 Existence of multiplicative inverse / Modulative property / Result
By definition of power, we find that a¹ as a is only only time.

Answer:
A. 35
Step-by-step explanation:
Each week has 7 days, and we have 5 weeks.
Week 1 has 7 days.
Week 2 has 7 days.
Week 3 has 7 days.
Week 4 has 7 days.
Week 5 has 7 days.
We can add all these together to get the total number of days: 7 + 7 + 7 + 7 + 7 = 7 * 5 = 35.
Thus, the answer is A.
Hope this helps!
<span>We want to check how many intersections line A and B have, that is, we want to check how many common solutions do these equations have:
</span>
i) 2x + 2y = 8
ii) x + y = 4
<span>
use equation ii) to write y in terms of x as : y=4-x,
substitute y =4-x in equation i):
</span>2x + 2y = 8
2x + 2(4-x) = 8
<span>2x+8-2x=8
8=8
this is always true, which means the equations have infinitely many common solutions.
Answer: </span><span>There are infinitely many solutions.</span><span>
