Answer 1

((х+у)/(х-у))/((х+у)(х+у))/((х-у)(х-у))=(х+у)*(х-у)(х-у)/(х-у)(х+у)(х+у)=(х-у)/(х+у)

Converting Expressions

To convert the given expressions, we'll need to analyze each expression and apply the appropriate transformations. Let's go through each expression one by one:

1. 7- (2 , 1). 6 .: - The expression seems to have a syntax error. It is not clear what the intended calculation is. Could you please provide more information or clarify the expression?

2. IBM Cognos Analytics - Reporting 11.0: - This is not an expression that can be converted. It appears to be the title of a software product.

3. ArcGIS Survey123: - The provided information does not contain an expression that needs to be converted. It seems to be related to a survey tool.

4. 3+2(6:3)x(y34): - This expression contains mathematical operations. To convert it, we need to follow the order of operations (PEMDAS/BODMAS): - First, we perform the division operation inside the parentheses: 6:3 = 2. - Then, we multiply 2 by the value of y34. - Finally, we add 3 to the result. - The expression can be converted to: 3 + 2 * y34.

5. log30,25+log316+log30: - This expression involves logarithmic functions. To convert it, we need to know the base of the logarithm and the values inside the logarithmic functions. - Without more information, it is not possible to provide a specific conversion for this expression.

6. sin(3π/8)*cos(π/8): - This expression involves trigonometric functions. To convert it, we can simplify it using trigonometric identities. - Using the identity sin(α)*cos(β) = 1/2*(sin(α-β)+sin(α+β)), we can rewrite the expression as: - sin(3π/8)*cos(π/8) = 1/2*(sin(3π/8-π/8)+sin(3π/8+π/8)). - Simplifying further, we have: - sin(3π/8-π/8) = sin(π/4) = √2/2. - sin(3π/8+π/8) = sin(π/2) = 1. - Therefore, the converted expression is: - (1/2)*(√2/2+1) = (2+√2)/4.

7. TypeError, Symbol, NaN, undefined: - This information does not provide an expression that needs to be converted. It seems to be discussing different concepts related to JavaScript, such as data types and values.

8. Google Play: - This is not an expression that can be converted. It appears to be related to the Google Play platform.

9. CRM Analytics: - This information does not provide an expression that needs to be converted. It seems to be related to customer relationship management (CRM) analytics.

10. null, undefined, NaN: - This information discusses different concepts related to JavaScript, such as null, undefined, and NaN. It does not provide an expression that needs to be converted.

Please provide more information or clarify the expressions so that we can assist you further with their conversion.
