<h3>Answer: -22</h3>
==========================================================
Explanation:
You could use synthetic division or polynomial long division to find the answer, but a much quicker way is to apply the remainder theorem.
That theorem says that if we divide p(x) over (x-k), then the remainder is p(k).
We're dividing over x+3, or x-(-3), so we can see that k = -3 in this case.
Plug this into the function
f(x) = x^3+5
f(-3) = (-3)^3 + 5
f(-3) = -27 + 5
f(-3) = -22 is the remainder

If you want to use polynomial long division or synthetic division, then check out the diagram below.
The logarithm value of log 1/2 462 to four decimal places is –8.8517.
<h3>What is a logarithm?</h3>The logarithm is the mathematical inverse function to exponentiation.
The logarithm of a number x is the exponent to another fixed term.
It is given the log of 462 to a base of 1/2.
= –8.8517
Therefore, the logarithm value of log 1/2 462 to four decimal places is
–8.8517.
