|dw:1441218251580:dw| first clarify the question you can use parenthesis write the expression then replace q with 2 and compute
triciaal
  • triciaal
based on the answer choices the question is (4 times a number q ) plus 25 4*2 = 8 8 + 25 = 33

yes its \[p = 8, Evaluate 4^{2} \div p.3\]
supercait10
  • supercait10
thats the problem
triciaal
  • triciaal
yes what does it mean? did you mean p^1/3?
supercait10
  • supercait10
idk its in the practice test
triciaal
  • triciaal
when p = 8 8^.3 =8^1/3 = 2

how it is on the test its p.3 thats what the test shows
triciaal
  • triciaal
I had to think yes 3p = 3 times p p.3 = p^.3
supercait10
  • supercait10
okay its fine just help me out of the third one the second doesn't matter
triciaal
  • triciaal
no its not fine if you don't understand!! I already did the third one
supercait10
  • supercait10
the second one is only worth half a point but still i have to do it the third and the first one are worth three points
triciaal
  • triciaal
next time the second one could cost you 50 points I think it comes down to understanding how to write see I missed it if it weren't for the choices then I had to "read in math"

nevermind i just failed the test anyways so it doesn't matter at this point it was a timed test and i failed so there is no point on telling me
triciaal

|dw:1441220648609:dw|
triciaal
  • triciaal
sorry you failed but if the question is not clear then it is different from what is expected and will be a different problem altogether
supercait10
  • supercait10
its fine
