Answer:
-2, -4, -3 + 2i, -3-2i
Step-by-step explanation:
Equaling the function to zero we have:
(x ^ 2 + 6x + 8) (x ^ 2 + 6x + 13) = 0
For the first parenthesis we have:
(x ^ 2 + 6x + 8) = 0\\(x + 4) (x + 2) = 0
Therefore the roots are:
x = - 4\\x = - 2
For the second parenthesis we have:
(x ^ 2 + 6x + 13) = 0
By completing squares we have:
x ^ 2 + 6x = -13
x ^ 2 + 6x + (\frac{6}{2}) ^ 2 = -13 + (\frac{6}{2}) ^ 2\\x ^ 2 + 6x + 9 = -13 + 9\\(x + 3) ^ 2 = - 4\\x + 3 = +/- \sqrt{-4}
Therefore the roots are:
x = -3 + 2i\\x = -3 - 2i

Answer:
Step-by-step explanation:
Let's look at what 10^100 and 100^10 are as numbers without exponents.
Ten raised to a positive integer exponent is a 1 followed by the number of zeros the exponent tells you. For example, 10^2 is 100, or 1 followed by 2 zeros, just like the exponent 2 tells you. 10^5 is 1 followed by 5 zeros, or 100,000. A googol is 10^100 which is a 1 followed by 100 zeros.
Let's use rules of exponents to understand what 100^10 is.
100^10 = (10^2)^10
To raise a power to a power, multiply powers.
100^10 = (10^2)^10 = 10^20
We know what 10^20 means. It is a 1 followed by 20 zeros.
A googol, 10^100, is a 1 followed by 100 zeros.
100^10 is the same as 10^20 or 1 followed by 20 zeros.
A googol is much, much greater than 100^10.
