Question

10у-(12у-(у-6)) при у=1/8 упростить выражение и найти его значение

Answer 1

10у-(12у-(у-6))=10у-12у+у-6=-у-6
-1/8-6=-61/8

Answer 2

To simplify the expression, we'll substitute the value of у with 1/8 and then perform the calculations step-by-step:

Given expression: 10у - (12у - (у - 6))

Step 1: Substitute у with 1/8 10(1/8) - (12(1/8) - (1/8 - 6))

Step 2: Simplify the expressions within parentheses 10/8 - 12/8 - (1/8 - 6)

Step 3: Continue simplification 10/8 - 12/8 - (-5/8)

Step 4: Further simplify (10 - 12 + 5)/8

Step 5: Perform the operations inside the parentheses (3)/8

Now, the expression is simplified to 3/8.

Finally, let's find its value by evaluating the expression when у = 1/8: 3/8 * 1/8 = 3/64

So, the value of the expression when у = 1/8 is 3/64.
