To simplify the terms you execute a prime factorization (divide exactly by the smallest prime possible until you reach 1) which in the case of 320 would be: 320=2*2*2*2*2*2*5. Every factor which exists twice can be taken out of the root. Simplify the many 2s into 2 equal readable factors: 320=2*2*2*2*2*2*5=8*8*5

\sqrt{320}=\sqrt{8*8*5}=8\sqrt{5}

\sqrt{162}=\sqrt{9*9*2}=9\sqrt{2}

\sqrt{108}=\sqrt{6*6*3}=6\sqrt{3}

\sqrt{125}=\sqrt{5*5*5}=5\sqrt{5}

\sqrt{63}=\sqrt{3*3*7}=3\sqrt{7}

\sqrt{432}=\sqrt{3*12*12}=12\sqrt{3}

\sqrt{112}=\sqrt{4*4*7}=4\sqrt{7}

\sqrt{98}=\sqrt{7*7*2}=7\sqrt{2}

\sqrt{12}=\sqrt{2*2*3}=2\sqrt{3}

\sqrt{726}=\sqrt{11*11*6}=11\sqrt{6}

\sqrt{300}=\sqrt{3*10*10}=10\sqrt{3}

\sqrt{8}=\sqrt{2*2*2}=2\sqrt{2}

\sqrt{27}=\sqrt{3*3*3}=3\sqrt{3}

\sqrt{18}=\sqrt{2*3*3}=3\sqrt{2}

\sqrt{196}=\sqrt{14*14}=14

\sqrt{30}=\sqrt{3*5*2}=\sqrt{3*10} and the end

Farmer Smith enclosed his rectangular pasture with fence that cost him $1.50 per linear meter. If his pasture is twice as long a
maria [59]

Answer:

$2,700

Step-by-step explanation:

Let the width of the pasture be x, this means that the length of the pasture will be 2x

The area of a rectangle is L * B

Hence,

x * 2x = 18,000

2x^2 = 180,000

x^2 = 90000

x = 300 meters

This means the length is 600 metres

Now, to get the length of the fence, we need to know the actual perimeter which is 2(L + B)

= 2 ( 300 + 600)

2 * 900 = 1,800 metres

The cost is thus 1,800 * $1.50 = $2,700

Julio bought a total of 20 medium and large pumpkins. If he spent $53 and bought 6 more large pumpkins as medium pumpkins, how m
Tatiana [17]
20 medium and large pumpkins

m ... number of medium pumpkins
l ... number of large pumpkins

20 = m + l
20 = m + (m + 6)
20 = 2 * m + 6
2 * m = 20 - 6
2 * m = 14
m = 7 medium pumpkins

l = 20 - 7 = 13 large pumpkins

Result: Julio bought 13 large pumpkins.

Alice Correa bought three yards of cloth to make a dress the cloth was on sale for a dollar 93 per yard how much did Alice pay f
alexandr1967 [171]
To solve for the total amount that Alice paid for the 3 yards cloth, multiply the cost per yard with the additional 5% to number of yards. 5% of 93 is 4.65. The total cost per yard of cloth is 97.65. Multiplying the total cost with 3 will give 292.95. Thus, Alice paid 292.95 dollars in total.
