(23/7+61/3)_34/3what the answer​

Mathematics
1 answer:
Keith_Richards [23]2 years ago
3 0
23/7+61/3 is done first due to PEMDAS
so the lcm of 7 and 3 is 21
So 23*3 + 61*7 divide the whole by 21 which is 7*3
The answer will come out to 496/21
Then outside the bracket the whole is times 34/3
So 34/3*496/21=
16864/64
We can’t simplify it more so that’s the answer

What is the simplest radical form of the expression? (8x5y3)2/3
kirza4 [7]

The simplest radical form of the expression is \mathbf{40 ^{2/3}x^{{10}/{3}}y^2}.

<h3>What is the simplification of power indices?</h3>

When we have indices in the form \mathbf{ax^{2/3}}, we are going to find the cube root of the (ax)². This can be mathematically expressed as:

\mathbf{=(\sqrt[3]{ax})^2 }

From the given information:

\mathbf{=(8x^55y^3)^{2/3}}

\mathbf{=(\sqrt[3]{8x^55y^3} } )^2

\mathbf{=(\sqrt[3]{40x^5y^3} } )^2

= (\sqrt[3]{40x^5} \times  \sqrt[3]{y}^3)^2

\mathbf{= 40 ^{2/3}x^{{5*2}/{3}}y^2}

\mathbf{= 40 ^{2/3}x^{{10}/{3}}y^2}

Is 3/4y=9 true or false
amm1812

<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3

Answer:

Let's solve your equation step-by-step.

3 / 4 y = 9

Step 1: Multiply both sides by 4/3.

(4 / 3 ) * ( 3 / 4 y ) = ( 4 / 3 ) * ( 9 )

y = 12

Answer:

y = 12

<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3

Insert 12 to the y value:

3 / 4 ( 12 ) = 9

9 = 9

True

<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3<3

Find the x-values that are solutions of the equation 5cot^2x-15=0
julia-pushkina [17]
First solve for the trig function 'cot'
cot^2 x = \frac{15}{5} = 3

Next take the sqrt of both sides (include plus/minus)
cot x = \pm \sqrt{3}

Now take reciprocal of both sides, this will change trig function to 'tan'
(cot = 1/tan)

tan x = \pm \frac{1}{\sqrt{3}} = \pm \frac{\sqrt{3}}{3}

Finally use the unit circle or inverse tan on your calculator to find x.
There will be 4 solutions, one for each quadrant.

x = \frac{\pi}{6}, \frac{5\pi}{6}, \frac{7\pi}{6}, \frac{11\pi}{6}
