Step-by-step explanation:
X^n ×X^n=X^10
X^n+n=X^10
X^2n=X^10
2n=10
n=10÷2
n=5

Answer:

Step-by-step explanation:
When we solve for an equation, our goal is to find the value of the variable. Any variable can be used, but for the time being let’s assume we use
.
We can algebraeically solve equations until we get the value of x - in which we will have x equal to something.
Say we have the equation
. Our goal is to find the value of
. <u>We can do this by getting x isolated on one side so we have something equal to x</u>.
We can subtract 5 from both sides and divide both sides by 5.

We now know the value of
since it’s on one side of the equation.

Step-by-step explanation:
The time difference t between 12.30pm and 3.30pm is 3h.
Let the distance to Marat's house be s.
The equation to calculate velocity v is given by:
v = distance / time.
Now you can write an equation for the time difference t and use the two velocities and the 90 min(= 1.5h) she stays:
3 = s/12 + 1.5 + s/2.3
Solve this equation for s:
(1/12 + 10/23)* s = 1.5
s = 2.9
