4.561, 4.562, 4.563, 4.564, 4.560
0.578 rounded to the nearest tenth would be 0.6, since the 7 in the hundredths spot is higher than 5.
Answer:
51
Step-by-step explanation:
Expanding the left side gives
which gives two solutions,
and
. But if
, then
, but this number isn't real, so
is an extraneous solution. Meanwhile if
, you get
, so this solution is correct.
"Potential solutions" might refer to both possibilities, but there is only one actual (real) solution.
