Answer:
Step-by-step explanation:
Doing this the long way, write a^12 as a product of "a"s
a^12 = a * a * a * a * a * a * a * a * a * a * a * a
Now group them into groups of 4
a^12 = a * a * a * a * a * a * a * a * a * a * a * a
There are 3 groups of 4 so you can write it as [(a^4)]^3 which is a cube
Now do the same thing with groups of 6s
a^12 = a * a * a * a * a * a * a * a * a * a * a * a
a^12 = (a^6)^2
So the two answers are
Perfect cube: [(a^4)]^3
Perfect square: (a^6)^2
The coefficient is the number 6/7.
Answer:
87.5%
Step-by-step explanation:
To find a percentage of questions correct divide the number of correct answers by the total number of questions and then multiply that by 100.
(35/40)100=87.5
We have to multiply 54 * 23, and check where the mistake is.
We start by multiplying 54 by 3, and it gives us 162
Then, we multiply 54 by 20, and it gives us 1080.
Then, we have to add these two results:
The mistake is where 6 is added to 8. It does not give 13, but 14.
The 1 of the 10 goes adding above the 1 in 162.
The result is 1,242.
