When there is multiplication, we add the powers.. But when there is division, we subtract the powers. Therefore:

3^8 x 3^4 is 3^8+4= 3^12 (this is the numerator)

3^2x3^8 is 3^ 2+8= 3^10 (this is the denominator)

Now since there is a division bar we obviously have to divide the numerator: 3^12 by the denominator: 3^10. [Remember division requires subtraction of powers] therefore:
3^12 \ 3^10 = 3^12-10
= 3^2. (=9)
And is not given as 9 since it is not in index form therefor answer is 3 power of 2 (3^2)
Hope this is helpful for you!

Answer:

Step-by-step explanation:

Just multiply the numerator together using a calculator (for ease) then multiply the denominators including the powers. Once you did this part properly you should get,

531441/59049

= 9

Answer:

$x = 6$

Step-by-step explanation:

$\frac{2}{3} x + 4 = 8 \\ \frac{2x}{3} = 8 - 4 \\ \frac{2x}{3 } = 4 \\ 2x = 4 \times 3 \\ 2x = 12 \\ x= 6$

Answer:

(i) U' = Φ

(ii) A∩A' = Φ

(iii) A – ( B U C) = {5,7,9}

(iv) A' U ( B U C ) = {2,4,6,8,10}

(v) A' U ( B' ∩ C') = {2,4,5,6,7,8,9,10}

The speed intervals such that the mileage of the vehicle described is 20 miles per gallon or less are: v ∈ [10 mi/h, 20 mi/h] ∪ [50 mi/h, 75 mi/h]

<h3>How to determine the range of speed associate to desired gas mileages</h3>

In this question we have a quadratic function of the gas mileage (g), in miles per gallon, in terms of the vehicle speed (v), in miles per hour. Based on the information given in the statement we must solve for v the following quadratic function:

g = 10 + 0.7 · v - 0.01 · v² (1)

An effective approach consists in using a graphing tool, in which a horizontal line (g = 20) is applied on the maximum desired mileage such that we can determine the speed intervals. The speed intervals such that the mileage of the vehicle is 20 miles per gallon or less are: v ∈ [10 mi/h, 20 mi/h] ∪ [50 mi/h, 75 mi/h].
