Question

3x+¹/2x = 6 find the value of 8x³+¹/27³​

Answer 1

Answer:

So 3x+1/2x=5

Solve this equation like any other:

First, multiply both sides by 2x to get rid of the denominator:

3x+1 = 10x

Subtract 3x from both sides:

1 = 7x

Divide by 7:

x = 1/7

now, plug this value for x into the other equation:

8x^3 + 1/27x^3

Remember, the exponents are being applied ONLY to x, and NOT the coefficient of x!

8*1/343 + 1/19683

8/343 + 1/19683

There’s your answer. I won’t bother to find common factors because 19683 is a headache to factor because of its size.

Step-by-step explanation:

Let’s start by simplifying 3x+1/2x =5

3x+1/2x = 5

3x+1 = 10x

1 = 7x

x = 1/7

So the value of x is 1/7. Now we substitute 1/7 into our second equation, 8x^3+1/27x^3.

8x^3+1/27x^3

(8/343 + 1)/(27/343)

(351/343)/(27/343)

351/27
