6a to the 3/4 power a=16

Mathematics
1 answer:
Katarina [22]3 years ago
6 0

Answer:

The answer is 48

Step-by-step explanation:

* Lets explain how to solve the problem

- The radical can be written as a fraction power:

 \sqrt[n]{x^{m} }=x^{\frac{m}{n}}

- We can simplify the fraction power by factorize the base of the power

 to numbers divisible by the power if it could

- Ex: 25^{\frac{1}{2}} we can factorize 25 to 5² and then

 make [(5)^{2}]^{\frac{1}{2}}=(5)^{2*\frac{1}{2}}=5

* <u><em>Lets solve the problem</em></u>

- We want to find the value of 6a^{\frac{3}{4}} , where a = 16

- Substitute the value of a by 16

∴ 6(16)^{\frac{3}{4}}

- Lets factorize 16

∵ 16 can be written as 2 × 2 × 2 × 2

∴ 16=2^{4}

- Replace 16 by 2^{4}

∴ 6(2^{4})^{\frac{3}{4}}=6(2^{4*\frac{3}{4}})=6(2^{3})

- Now solve 2³

∵ 2³ = 8

∴ 6(8) = 48

∴ 6a^{\frac{3}{4}} = 48

* The answer is 48

Joe bought 5 apples and 4 bananas for $6. Dawn bought 3 apples and 6 bananas for $6.30. How much foes each apple and each banana
zepelin [54]

Answer:

Apple = $0.6

Banana = $0.75

Step-by-step explanation:

Let us represent Apple by A and Banana by B

For Joe,

5A + 4B = 6       (1)

For Dawn

3A + 6B = 6.3     (2)

To eliminate A, Multiply equation (1) by 3 and equation (2) by 5

15A + 12B = 18          (3)

15A + 30B = 31.5       (4)

subtracting equation (4) from (3)

15A - 15A +12B - 30B = 18 - 31.5

-18B = -13.5

divide through by -18

-18B/-18 = -13.5/-18

B = 0.75

substitute 0.75 in equation (1)

5A + 4B = 6

5A + 4(0.75) = 6

5A + 3 = 6

subtract 3 from both sides

5A + 3 - 3 = 6 - 3

5A = 3

divide through by 5

5A/5 = 3/5

A = 0.6

FG ∥ CB, A ∈ FG, D ∈ AB, E ∈ AC
andrey2020 [161]

Answer:

The value of x is 31^{\circ}.

Step-by-step explanation:

Please look at the figure attached to get more clear solution.

We have given:

FG||CB

And the line that cut the parallel line is transversal so, here BA is transversal

And alternate interior angles on transverse line are equal

So, ∠1=∠4

And ∠4=28^{\circ}

Hence,  ∠1=∠4=28^{\circ}

And On FG the sum of angles will be 180^{\circ}

∠3+∠2+∠1=180^{\circ}

90^{\circ}+∠2+28^{\circ}=180^{\circ}

Hence, ∠2=62^{\circ}

Now, we know that the sum of interior angles is equal to the exterior angle:

Therefore, ∠2+∠5=∠6+∠7

62^{\circ}+3x=x+4x

On simplification we get:

2x=62^{\circ}

x=31^{\circ}

Hence, the value of x is 31^{\circ}.
