(0.9-n)sqrt(n)=-1.96

(0.9 - n) n = - 1.96

n \approx 2.21650 \dots

Solution steps

(0.9 - n) n = - 1.96

Expand

(0.9 - n) n : 0.9 n - n n

0.9 n - n n = - 1.96

Factor

0.9 n - n n : - n (n - 0.9)

- n (n - 0.9) = - 1.96

Square both sides:

n^{3} - 1.8 n^{2} + 0.81 n = 3.8416

n^{3} - 1.8 n^{2} + 0.81 n = 3.8416

Solve

n^{3} - 1.8 n^{2} + 0.81 n = 3.8416 : n \approx 2.21650 \dots

n \approx 2.21650 \dots

Verify Solutions:

n \approx 2.21650 \dots

True

The solution is

n \approx 2.21650 \dots

7 + 10 x + 4 = 47

x^{0.8} - 2 x = 10 x + 3

3 x - 2 = 10

x, ff = 4 x - 3

1 = 2 - t - 4
