Answer:
4^15/ b^21
Step-by-step explanation:
( b^7 / 4^5) ^ -3
b^7 ^ -3 / 4^5^-3
We know that x^y^z = x^ (y*z)
b^ (7*-3) / 4^(5*-3)
b ^ -21 / 4 ^ -15
We know that a^ -b = 1/ a^b
We do not like to leave negative exponents
1 * b^21 * 4 ^15
4^15/ b^21
Answer:
7.065 m ^ 2
8.935 m ^ 2
Step-by-step explanation:
The first thing is to calculate the surface of each one, that is, the area
For the room that is square, each side measures 4m, therefore:
As = 4 * 4 = 16 m ^ 2
The area of the carpet is that of a circle, that its area is the number pi times the radius squared, we know that the radius is half the diameter, therefore r = 3/2 = 1.5 m
replacing in the area formula
Ac = pi * r ^ 2 = 3.14 * 1.5 ^ 2
Ac = 7.065 m ^ 2
In other words, the area covered by the carpet is 7,065 m ^ 2 and the area not covered would be the subtraction between the area of the room minus the area of the carpet, that is:
16 m ^ 2 - 7.065 m ^ 2 = 8.935 m ^ 2
8.935 m ^ 2 would be the area that the carpet does not subside.
<em>So to solve for a variable, you have to isolate that variable onto one side.</em>
<h3>14.</h3>
Firstly, multiply both sides by j: 
Next, divide both sides by k and <u>your answer will be: 
</u>
<h3>15.</h3>
Firstly, add g on both sides: 
Next, multiply both sides by 5 and <u>your answer will be: 
</u>
<h3>16.</h3>
Firstly, subtract 5p on both sides: 
Next, divide both sides by 9 and <u>your answer will be 
</u>
