To evaluate mathematical expressions, follow the BODMAS (brackets, order, division/multiplication, addition/subtraction) rule.

6. Evaluate 4*4 - 14/2 + 6:

Step 1: Start by solving any calculations within parentheses or brackets. In this case, there are no parentheses or brackets.

Step 2: Next, calculate any divisions or multiplications from left to right.

Perform 14/2 = 7.

Step 3: Continue with any additions or subtractions from left to right.

Perform 4*4 = 16.

Perform 16 - 7 = 9.

Then, perform 9 + 6 = 15.

So, the evaluation of the expression 4*4 - 14/2 + 6 is 15.

7. Evaluate 2 * [1 + (19 + 13) / 4]:

Step 1: Start by solving any calculations within parentheses or brackets.

Perform 19 + 13 = 32.

Step 2: Perform any divisions or multiplications from left to right.

Perform 32 / 4 = 8.

Step 3: Continue with any additions or subtractions from left to right.

Perform 1 + 8 = 9.

Step 4: Multiply the result from Step 3 with the number outside the brackets.

Perform 2 * 9 = 18.

So, the evaluation of the expression 2 * [1 + (19 + 13) / 4] is 18.

8. Evaluate 50 + 25 / 5^2:

Step 1: Start by solving any calculations within parentheses or brackets. In this case, there are no parentheses or brackets.

Step 2: Perform any divisions or multiplications of powers (exponents) from left to right.

Perform 5^2 = 25.

Step 3: Perform any divisions or multiplications from left to right.

Perform 25 / 25 = 1.

Step 4: Perform any additions or subtractions from left to right.

Perform 50 + 1 = 51.

So, the evaluation of the expression 50 + 25 / 5^2 is 51.
