Step-by-step explanation:
<h3>Given</h3>
- a = 2i + 9j, b = –4i + 5j, c = i – 3j, d = 14j
<h3>To find</h3>
<h3>Solution</h3>
- (a – b) – (2d – c) =
- 2i + 9j - (–4i + 5j) - (2(14j) - (i – 3j)) =
- 2i + 9j + 4i - 5j - 28j + i - 3j =
- (2 + 4 + 1)i + (9 - 5 - 28 - 3)j =
- 7i + (-27)j =
- 7i - 27j
Answer:
To solve this you must first know how Log works.
When we say log1000 of base 10
Or
log1000=3
What we actually say is for the power 3(value on RHS) of 10(the base of log) we get 1000(the value on which log is performed).
So log2x=−5 (i am assuming base 10 since it is simple algebra) means that
2x=10−5
x=10−5/2
Do this simple calculation and you have it. If anything is unclear/incorrect feel free to comment.
The question is not written properly, so I will give the answer(s) I think would be suitable.
If you were trying to solve this
log2x=−5
⟹x=2−5
⟹x=132
But if you were trying to solve this
log2x=−5
⟹log102x=−5
⟹2x=10−5
⟹x=12×105=1200000
