What is the value of n in the equation shown below? 2^2 x 2^n = (2^4)^3

1 answer:

3 0

So 2^2*2^n=(2^4)^3
2^2= 4
2^4=16
Then 16^3=4096
Now what we have is 4*2^n= 4096
You need to get the 2^n by itself so divide out the 4
4096/4= 1024
2^n=1024
Now you need to do log to get rid of that exponent
Therefore: n=log2(2024) or n=10

ANSWER
n=10

In the school library, 28% of the books are non-fiction. If there are 1,224 fiction books in the library, what is the total numb

N76 [4]

Answer:

There are 1700 books in the library.

Step-by-step explanation:

If 28% of the books is non-fiction, that means the remaining 72% of books are fiction.

If 72% of the books are fiction, 1224/72 will give us 1%, which is 17.

If 1% is 17 books, then 17*100=100% of books.

There are 1700 books in the library.

Please help with my guided practice

qaws [65]

it's 88 I've been getting so mix up forgive me So the area of the square is 64. When you find the area of the triangle you multiply the base by its height, which is 6 by 8 and then you divide by two. 64+24=88

Da sofa is on sale for $98.60, which is 29% of the regular price. What is the regular price ?

yaroslaw [1]

Let the regular price be X
x\98.60 x 100=29%
100x\98.60=29(multiply both sides by 98.60 to remove the denominator
100x=2859.4(divide both sides by 100
x=28.594
regular price=$28.594

As – 16a, as – 4a3, 2a3 + 8a - 4a2 - 16

vfiekz [6]

Answer:

1) as-16a

taknig a as common

=a(s-16)

2)as-4a³

taking a as common

=a(s-4a²)

3)2a³+8a-4a²-16

taking common terms

=2a(a²+4)-4(a²+4)

=(2a-4)(a²+4)

again taking common

=2(a-2)(a²+4)

i hope this will help you :)
