How can the addition of a parenthesis be used to increase the value of the following expression?: 12-3^4-2/7+1

Answer 1

If you put the expression #12-3# in brackes, the value will increase.

The original expression is:

#12-3^4-2/7+1=12-81+5/7=-68 2/7#
If you put #12-3# in brackets the order of the operation changes, and so does the value:
#(12-3)^4-2/7+1#

Now first we have to calculate the value of expression in brackets:

#(12-3)^4-2/7+1=9^4-2/7+1=# #6561-2/7+1=6560 5/7+1=6561 5/7#

Answer 2

By adding parentheses to the expression, the order of operations can be altered, potentially changing the result. For example, by adding parentheses as follows: 12 - (3^4) - 2/7 + 1, the exponentiation operation (3^4) is performed before the subtraction, resulting in a different outcome compared to the original expression. This is because according to the order of operations, exponentiation takes precedence over addition and subtraction.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
