The area of a square is represented by the expression 16x^4y^8. What is the length of each side of this square

Leona [35]

Answer: $4x^2y^4$

Step-by-step explanation:

Given

The area of the square is $A=16x^4y^8$

Suppose a is the side length of the square

The area of the square is given by

$\Rightarrow A=(\text{side length})^2$

So, we can write

$\Rightarrow a^2=16x^4y^8\\\Rightarrow a=4x^2y^4$

length of each side is $4x^2y^4$

Mr. Hall deposited money into an account in which interest is compounded quarterly at a rate of 2.6%. How much did he deposit if

Amanda [17]

The formula of this equation would be $x_{0}$ * 1.026^16 = 7,160.06
So from this equation we know that $x_{0} = \frac{7,160.06}{1.026^{16} }$
Now we need to find the value of x, we need to multiply $x_{0}$ * 1.026 16 times. Which will bring us to your answer. $4,748.53
