Answer:
4 option D
Step-by-step explanation:
Note that log2(2^n)=n
Thus we have:
Log2(2)+log2(8)=1+log2(2³)=1+3=4
Answer:
4
Step-by-step explanation:
3- 3
23 - 3
20 / 5 = 4.
4 x 5 + 3 = 23, so X is 4.
Answer:
(x + 8) (x - 8)
Step-by-step explanation:
To factorise the expression follow the steps:
Think the factorising means you want like:-
( x + _ ) ( x + _ )
Now, add the numbers to get 0 & multiple together to get -64
-64 = 8 x -8
8 + -8 = 0
Now fill the numbers in the factorising mean which will give you,
( x + _ ) ( x + _ ) --> ( x + <u>8</u> ) ( x - <u>8</u> )
Therefore, the answer will be: ( x + <u>8</u> ) ( x - <u>8</u> )
I hope this will help you :)
