If you mean 5^2 and not 5^2i then
5^2 just means 5 times itself,twice or 5 times 5 or 25
if you meant 5^2i
i=√-1
so law of exponents says a^(xz)=(a^x)^z so
5^2i=(5^2)^i or (25)^i
the answer (if you wanted 5^2i) is 25^i
IF YOU MEANT 5^2 then the answer is 25
Answer: I assume this ques was formatted like this originally. 4/10 = 2. If so the answer is 5 making the second fraction 2/5. Let me know if this is not the case. Hope this helps!

Answer:
x = (c -mp)/g
Step-by-step explanation:
Subtract the term not containing x, then divide by the coefficient of x.
gx +mp = c . . . . . given
gx = c - mp . . . . . subtract mp
x = (c -mp)/g . . . . divide by g

<em>Comment on the process</em>
This process can be described various ways. A usual description is "get the x term by itself on one side of the equal sign, then divide by the x-coefficient."
I like a more general description of the solution to "solve for" problems: undo what is done to the variable, in reverse order.
Here, the variable x is multiplied by g, then added to mp. To undo those operations (in reverse order), first we undo the addition of mp. We accomplish that by subtracting mp, or by adding the opposite of mp, as you wish.
Having done that, we undo the multiplication by g by dividing by g.
(gx)/g = (c -mp)/g
x = (c -mp)/g
The steps we actually perform here are identical to the steps in "get the x-term by itself, ...". However, the process we have described can be applied to any sort of equation, not just a 2-step linear equation.
Answer:
36°, 63°, 81°
Step-by-step explanation:
Let 4x = measure of angle 1
7x = measure of angle 2
9x = measure of angle 3
The sum of the measures of the angles of a triangle = 180
So 4x + 7x + 9x = 180
20x = 180
x = 9
4x = 36 = measure of angle 1
7x = 63 = measure of angle 2
9x = 81 = measure of angle 3
Check: 36 + 63 + 81 = 180
