Question

* - (x) степень 4×9*-7×12*+3×16*=0

Answer 1

7 * 10-1 + 4 * 10-3 + 9 * 10-4

Решим уравнение (по частям) :

7 * 10-1 = 7 / 101 = 7 / 10 = 0.7

4 * 10-3 = 4 / 103 = 4 / 1000 = 0.004

9 * 10-4 = 9 / 104 = 9 / 10000 = 0.0009

Теперь все сложим:

0.7 + 0.004 + 0.0009 = 0.7049

Ответ: 0.7049

Answer 2

To solve the equation: * - (x) степень 4×9*-7×12*+3×16*=0, let's break it down step by step.

The given equation is: * - (x) степень 4×9*-7×12*+3×16*=0

It seems like there might be some misunderstanding in the notation, as it's not clear what the "×" and "" symbols represent. I'll assume that "×" is multiplication, and "" is the symbol used to denote exponentiation.

Rewriting the equation with standard mathematical notation:

x^4 * 9 - 7 * 12^3 + 3 * 16^2 = 0

Now, we'll solve the equation:

Step 1: Calculate the exponents 9^4 = 6561 12^3 = 1728 16^2 = 256

Step 2: Substitute the calculated values back into the equation: x^4 * 6561 - 7 * 1728 + 3 * 256 = 0

Step 3: Perform the multiplications and additions: 6561x^4 - 12096 + 768 = 0

Step 4: Simplify the equation further: 6561x^4 - 11328 = 0

Step 5: Move the constant term to the other side of the equation: 6561x^4 = 11328

Step 6: Solve for x: x^4 = 11328 / 6561

Step 7: Take the fourth root of both sides to find x: x = (11328 / 6561)^(1/4)

Using a calculator to evaluate this value, we get:

x ≈ 1.551

So, the approximate value of x that satisfies the equation is x ≈ 1.551.
