Thanks
Didn't know for certain so I had to ask.
Hello, Hayley and guest (I don't know your name or are you the same person?)
2+2=4 or 2^2=4 2*2=4 1+1+1+1=4 1*4=4 so 2+2=4 2 is the only number that times itself (2*2=4) to its own power (2^2=4) and evn plus itself(2+2=4) all equal the same number
Lets do this in steps
so lets do the sqrts first
the sqrt of 36 is 6 , sqrt of 64 is 8 and sqrt of 4 is 2
so now you have
7*6*8/4*2+6 so 7*6=42
42*8=336
336/4=84
now 84*2=168
168+6=174 voila!
Agreed CPhill when I attempt to help (rarely) I try to show the steps and everyonce in a while try to leave them a solving point.
I think you trashed him enough for now.
Nope nothing.
Don't know about mars but to reach earth it takes about 8 minutes
Lets split this into groups.
-83+-9=-92
next
-92--12=-80
-80+-17=-97
then
-97-2=-99
-99+-24=-123
finally
-123+-73=-196
+498
