Question

(1^3/5-1,75):0,2 40^11*4^-11/10^10

Answer 1

Ответ:1. -2,75             2. 10

Пошаговое объяснение: 1)  (1³:5-1,75) :0,2=(1/5-0,75):0,2=(0,2-0,75):0,2=

= -0,55:0,2= -5,5:2= -2,75.

2) (40¹¹ * 4⁻¹¹):10¹⁰= (4¹¹ * 10¹¹ * 4⁻¹¹):10¹⁰= 10¹¹:10¹⁰=10.

Answer 2

Let's break down the given expression step by step:

1. (1^3/5 - 1.75):0.2

First, let's simplify the expression within the parentheses: 1^3/5 = 1 1 - 1.75 = -0.75

Now, we can substitute these values back into the original expression: (-0.75):0.2

Dividing -0.75 by 0.2 gives us: -0.75 / 0.2 = -3.75

Therefore, the result of the expression (1^3/5 - 1.75):0.2 is -3.75.

2. 40^11 * 4^-11 / 10^10

Let's simplify each term individually: 40^11 = 419,430,400,000,000,000,000,000,000 4^-11 = 1/4^11 = 1/4,194,304 10^10 = 10,000,000,000

Now, we can substitute these values back into the original expression: 419,430,400,000,000,000,000,000,000 * (1/4,194,304) / 10,000,000,000

Simplifying the fraction within parentheses: 1/4,194,304 ≈ 0.000000238418579

Substituting this value back into the expression: 419,430,400,000,000,000,000,000,000 * 0.000000238418579 / 10,000,000,000

Performing the multiplication and division: ≈ 100

Therefore, the result of the expression 40^11 * 4^-11 / 10^10 is approximately 100.

In summary:

1. (1^3/5 - 1.75):0.2 = -3.75
2. 40^11 * 4^-11 / 10^10 ≈ 100
