Question

(-6√7/4+√324/2×√0,16/0,2):√25

Answer 1

лучше чем ничего......

Answer 2

Let's simplify the expression step by step:

First, let's simplify the terms within the parentheses:

• The term "-6√7/4" can be simplified by dividing -6 by 4, resulting in -3/2√7.
• The term "√324/2" simplifies to √(324/2) = √162 = 9√2.
• The term "√0.16/0.2" simplifies to √(0.16/0.2) = √0.8 = √(0.8 * 1) = √(0.8 * 5/5) = √(4/5) = 2/√5.

Now, let's substitute these values back into the expression: ((-3/2√7) + (9√2 * 2/√5)) / √25

Next, let's simplify further: ((-3/2√7) + (18√2/√5)) / 5

To rationalize the denominator, we multiply the numerator and denominator by √5: ((-3/2√7) + (18√2/√5)) * (√5/√5) / (5 * √5/√5)

This simplifies to: ((-3√5)/(2√7) + (18√10)/(5√5)) / (5√5)

Now, let's combine like terms in the numerator: ((-3√5) + (18√10)) / (2√7 * 5√5)

Finally, let's simplify further by multiplying the denominators: ((-3√5) + (18√10)) / (10√35)

This is the simplified form of the expression: (-3√5 + 18√10) / (10√35)
