Answer:
= - 12 + 316 i
Step-by-step explanation:
Given that -
z = 3 + i
<em>
= 
</em>
<em> = 9 + 
+ 6 i</em>
<em> = 9 - 1 + 6 i</em>
= 8 + 6 i
<em>
= × z</em>
<em> = ( 8 + 6 i ) × ( 3 + i )</em>
<em> = 24 + 8 i + 18 i + 6 i²</em>
<em> = 24 + 26 i - 6</em>
= 18 + 26 i
= ×
<em> = ( 8 + 6 i ) × ( 18 + 26 i )</em>
<em> = 144 + 208 i + 108 i + 156 i²</em>
<em> = 144 + 316 i -156</em>
= - 12 + 316 i
3(6x+2) <9
Use distributive property:
18x + 6 < 9
Subtract 6 from both sides
18x < 3
Divide both sides by 18
X < 3/18
Simplify:
X < 1/6
Answer:
0 isnt a number loll
Step-by-step explanation:
B
Do the exponents first. 10 to the -4 is 1/10000 or 0.0001 and 10^ -5 is 0.00001. You end up with (1.7*0.0001)(5*0.00001) which is 0.00017*0.00005 which is 0.0000000085 or 0.085*10^-8
