Question

(а+3,62в квадрате) : 0,25-а в кубе :40 При:а=0,4

Answer 1

0,4+3,62²:0,25-0,4³:40=13,5044: 0,186:40= 1,8151075269

Answer 2

To solve this equation, let's substitute the value of a = 0.4 and perform the calculations step by step:

Step 1: Substitute the value of a = 0.4 into the equation: (0.4 + 3.62b^2) / (0.25 - 0.4^3) = 40

Step 2: Simplify the expression: (0.4 + 3.62b^2) / (0.25 - 0.064) = 40 (0.4 + 3.62b^2) / 0.186 = 40

Step 3: Multiply both sides of the equation by 0.186 to eliminate the denominator: 0.4 + 3.62b^2 = 40 * 0.186 0.4 + 3.62b^2 = 7.44

Step 4: Subtract 0.4 from both sides of the equation: 3.62b^2 = 7.44 - 0.4 3.62b^2 = 7.04

Step 5: Divide both sides of the equation by 3.62 to isolate b^2: b^2 = 7.04 / 3.62 b^2 ≈ 1.9419

Step 6: Take the square root of both sides of the equation to solve for b: b ≈ √1.9419 b ≈ 1.3933 (rounded to four decimal places)

Therefore, when a = 0.4, the solution to the equation is b ≈ 1.3933.
