To solve the equation √n/4 = √(5-n), we can start by squaring both sides of the equation:

(√n/4)^2 = (√(5-n))^2

Canceling out the square roots gives us:

(n/4)^2 = (5-n)

Expanding both sides of the equation further, we have:

n^2/16 = 25 - 10n + n^2

Now, let's simplify the equation by multiplying both sides by 16 to eliminate the fraction:

n^2 = 400 - 160n + 16n^2

Rearranging the equation by combining like terms:

15n^2 + 160n - 400 = 0

To simplify this quadratic equation, we can divide through by 5:

3n^2 + 32n - 80 = 0

Now, we can try to factorize the equation:

(3n - 8)(n + 10) = 0

Setting each factor equal to zero gives us two possible solutions:

3n - 8 = 0

n + 10 = 0

Solving for n in each case:

3n = 8

n = 8/3

n = -10

Therefore, the possible solutions for n are n = 8/3 and n = -10.

I HOPE THIS HELPS.

okay so question 2

To solve the equation √m - 4 = √10-m, we can start by isolating one of the square roots on one side of the equation.

Let's begin by moving the square root term involving m to one side:

√m - √10 + m = 4

Next, let's square both sides of the equation to eliminate the remaining square roots:

(√m - √10 + m)^2 = 4^2

Expanding the squared term gives us:

(m - 2√(10)m + 10 - 4√m + 2m√(10) + m^2) = 16

Rearranging the equation and simplifying like terms:

m^2 + 3m√(10) - 4√m - 2√(10)m - 14 = 0

Factoring out common factors:

(m^2 + m(3√10 - 2√10) - 4√m - 14 = 0

Simplifying further:

(m^2 + m√10 - 4√m - 14) = 0

Now, at this point, it is difficult to directly factor or simplify the equation further. One way to proceed is to use numerical methods or solvers to find an approximate value for m that satisfies the equation. Alternatively, graphical methods can also be used to find a solution.
