8^3*8^-5*8^y=1/8^2, what is the value of y in the product of powers below?
Aleks04 [339]

For this case we have that by definition of multiplication of powers of the same base, the same base is placed and the exponents are added:

a ^ n * a ^ m = a ^ {n + m}

So, we can rewrite the given expression as:

8 ^ {3-5 + y} = \frac {1} {8 ^ 2}\\8 ^ {- 2 + y} = \frac {1} {8 ^ 2}

So, if y = 0:

8 ^ {- 2} = \frac {1} {8 ^ 2}\\\frac {1} {8 ^ 2} = \frac {1} {8 ^ 2}

Equality is met!

Answer:

y = 0

The base of a regular hexagonal pyramid has an apothem length of 3√ in. What is the exact area of the base of the pyramid?
12345 [234]
1. To solve this problem you must apply the formula for calculate the area of a regular hexagon given the apothem, which is shown below:

 A=(Perimeter x Apothem)/2

 2. You have the apothem, so you can calculate the perimeter. First, you have to know the lenghts of the sides:

 Tan(30°)=x/√3
 x=1

 Side=2x
 Side=2

 Perimeter=2x6
 Perimeter=12

 3. Then, you have that the area of the base is:

 A=(Perimeter x Apothem)/2
 A=12x√3/2
 A=6√3
 A=10.39
 B=10.39 cm²

 The answer is: B=10.39 cm²
