Question

5*(810:9-х*3)=40*8-5

Answer 1

х=1035 я думаю

 это х*3 или х в третьей степени

 

Answer 2

4050 / 9 - x^3 = 315

9 - x^3 = 4050 * 315 = 1275750

- x^3 = 1275741

X = корень третьей степени из числа 1275741

 

 

 

 

 

 

Answer 3

To solve the equation 5*(810:9 - x*3) = 40*8 - 5, we can follow the order of operations (PEMDAS/BODMAS) to simplify the expression on both sides of the equation.

Simplifying the left side of the equation:

First, let's simplify the expression inside the parentheses on the left side: 810 divided by 9 equals 90, and then we subtract x multiplied by 3 from it.

So, the expression inside the parentheses becomes: 90 - 3x

Now, we can rewrite the equation as: 5 * (90 - 3x) = 40 * 8 - 5

Next, we can simplify the expression within the brackets: 90 - 3x

Simplifying the right side of the equation:

The right side of the equation is: 40 * 8 - 5

We can perform the multiplication first: 40 * 8 equals 320

So, the right side of the equation becomes: 320 - 5

Final equation:

Now we have: 5 * (90 - 3x) = 320 - 5

Solving the equation:

To solve the equation, we need to isolate the variable x.

Let's simplify the left side of the equation: 5 * (90 - 3x) = 320 - 5

Distribute the 5 on the left side: 450 - 15x = 320 - 5

Now, let's simplify the right side of the equation: 450 - 15x = 315

Next, we can subtract 450 from both sides to isolate the variable: -15x = 315 - 450

Simplifying the right side: -15x = -135

To solve for x, we divide both sides by -15: x = -135 / -15

Simplifying the division: x = 9

Solution:

The solution to the equation 5*(810:9 - x*3) = 40*8 - 5 is x = 9.
