16x^2 + 40x + 25
(4x)^2 + 2(4x)(5) + 5^2
(4x + 5)^2
The answer is: (4x + 5)^2.
Answer: Options a,b are correct
Explanation:
We can check the true statements with thye help of logarithmic rules
1. product rule log(xy) = logx+logy
2.quotient rule 
3. Exponent rule 
Option a is satisfying product rule
Option b is satisfying exponent rule
Option c is discarded because
not equal to p*LogM
Option D is discarded because logM-logN =
is not equal to log(M-N)
Hence, Option a and b are correct.

bearing in mind that "t" cannot be less than 0.
Answer:

Answer:
8.68·10^7
Step-by-step explanation:
Scientific notation is a number with no zeros between 1-10 that is multiplied by a number of 10's so here we just take away 868 and add a decimal point to make it between 1-10 8.63
then we count our zeros and add the amount of numbers behind the decimal point
thats how many 10's there will be(7)
our answer is 8.63·10^7
