Answer:
subtract 6.4
Step-by-step explanation:
what you have to do is isolate the variable, (n), so get rid of the 6.4 from each side, then divide both sides by 3.5
The sum of first 8 terms of series is -130208
<em><u>Solution:</u></em>
Given that,
2 - 10 + 50 - 250 , ....
n = 8
Find the common ratio between a term and its previous term

Thus common ratio is same
This is a geometric series
<em><u>The sum of terms of geometric sequence is given as:</u></em>

Where,
r is the common ratio
n is the nth term
is the first term of series
From series,

Therefore,

Thus sum of first 8 terms of series is -130208
Answer:
Step-by-step explanation:
Use the change-of-base rule.
log₂(62) = ln(62)/ln(2)
Answer: B. -2x^4y^3
Step-by-step explanation:
Multiply the variables by each other.
-2x^3 * x = -2x^4
y * y^2 = y^3
