How do you solve #-5+ ( - 7) ( - 2) - ( - 3)^{3}#?

Answer 1

#-5+(-7)(-2)-(-3)^3=36#

The order of operations in such a case is given by PEMDAS which lists the operations which should be done first. It stands for Parentheses, Exponents, Multiplication, Division, Addition and Subtraction. Hence we will do operations in this order.

#-5+(-7)(-2)-(-3)^3# (Here #(-7)(-2)# means #(-7)xx(-2)#
= #-5+(-7)xx(-2)-(-3xx-3xx-3)#
= #-5+(-7)xx(-2)-(-27)#
= #-5+14+27#
= #-5+41#
= #36#

Answer 2

To solve the expression ( -5 + (-7) \times (-2) - (-3)^3 ):

  1. Calculate each operation according to the order of operations (PEMDAS/BODMAS): a. Start with the exponentiation: ( (-3)^3 = -3 \times -3 \times -3 = -27 ). b. Multiply the negative numbers: ( (-7) \times (-2) = 14 ). c. Now, substitute the results into the original expression: ( -5 + 14 - (-27) ). d. Perform subtraction: ( -(-27) = 27 ). e. ( -5 + 14 + 27 ).
  2. Add the numbers together: ( -5 + 14 + 27 = 36 ).

Therefore, the solution to ( -5 + (-7) \times (-2) - (-3)^3 ) is ( 36 ).

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.
