That's not an inequality.

$8/3 - 6 = 8/3 - 18/3 = (8-18)/3 = -10/3$

$\ln (5^{2x})=\ln 25\\ 2x \ln 5 = \ln 25\\ x \ln 5^2 = \ln 25\\ x = \ln25 / \ln 25 = 1$

$\text{Example:} \sqrt[3]{8}\\ \text{You identify }8 = 2^3 \sqrt[3]{8}\\ = \sqrt[3]{2^3}\\ = 2$

Remembering that 1/4 = 0.25.....

5/4 = 1/4 x 5 = 0.25 x 5 = 1.25

The angle formed by the diagonal and the side will always be 45 degrees.

sin 45 = 7 / diagonal

diagonal = 7sqrt(2)

a(0)=50

a(1)=1/2 x 50 + 10 = 35

a(2)= 1/2 x 35 + 10 = 55/2

a(3)= 1/2 x  27.5 + 10 =75/4

a(n) = $50 - 30\overbrace{(1/2+1/4+1/8+.......)}^{n}$= $50 - 30(\dfrac{2^n-1}{2^n})$

No.
