need help with algebra expresions

Patrick W.

Help me out Mariel..
 
Are you asking -7×(-4)÷142 ?
this could also be written (-7)(-4)/14^2
 
I guess I'm just confused about whether 14 the only number being raised to the power of 2?
Because if that is the case, the order of operations says that we'll do exponents first, then multiplication and division together, from left to right.
 
-7×(-4)÷142
-7×(-4)÷196
28÷196
28/196=1/7

-7 x -4 = 28


28/14 = 2


2^2 = 4


UNLESS you meant


14^2 = 196


then 28/196 = 7/49= 1/7


or did you mean 142? not 14^2? or the whole expression squared? 3 different answers


28/142 = 14/71 square it gets 196/5041


so, either 4, 1/7 or 196/5041


1/7 is probably what you want
