What is the value of #2^3+8-:4*2+3#?

Answer 1

#15#

Count the number of terms first. Each term will simplify to to a single answer and they are only added or subtracted in the last line.

Within in a term - do brackets first, then the strongest operations (powers or roots), and then multiplication and division.

#color(purple)(2^3)color(red)( + 8div4xx2)color(blue)(+3)" "larr# there are 3 terms.
=#color(purple)(8)color(red)( + (8xx2)/4color(blue)(+3)#
=#color(purple)(8)color(red)( + 4)color(blue)(+3)" "larr# add from left to right
=#15#

Answer 2

To calculate the value of the expression "2^3 + 8 - 4 * 2 + 3", follow the order of operations (PEMDAS/BODMAS):

  1. Evaluate exponents: (2^3 = 8).
  2. Perform multiplication and division from left to right: (8 - 4 \times 2 = 8 - 8 = 0).
  3. Finally, perform addition and subtraction from left to right: (0 + 3 = 3).

So, the value of the expression is (3).

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.
