Taking the square root of 618 we get
<span>
<span>
<span>
24.8596057893
</span>
</span>
</span>
and
<span>
<span>
<span>
-24.8596057893
</span>
</span>
</span>
Rounding to nearest tenth
24.9 and
-24.9
First u divide by 2 then after that u divide by two agian and that should be your answer
8.9-3.3j=-2.2j+2.3
add 3.3j to both sides
8.9=1.1j+2.3
subtract 2.3 from both sides
6.6=1.1j
divide both sides by 1.1
6=j
