tolong jawab dengan caranya ya....terima kasih

A2x=2
Ax= 1
A5x=5
A-5x=-5
A3x=3
A-3x=-3

Jadi
5-(-5)
———
3+(-3)
= 5+5
———
3-3
=10

= (a^(4x+x) - a^(-4x-x))/(a^(2x+x) + a^(-2x-x))
= (a^(4x).a^x - a^(-4x).a^(-x)) / (a^(2x).a^(x) + a^(-2x).a^(-x))
= (2^2.√2 - (1/2)^2.(1/√2)) / (2.√2 + (1/2)(1/√2))
= (4√2 - 1/(4√2)) / (2√2 + 1/(2√2))
= ( ( (4√2)² - 1)/(4√2))) / ((4√2.2√2) + 1.2)/4√2))
= ((4√2)² - 1) / (4√2.2√2 + 2)
= (16.2 - 1) / (8.2 + 2)
= 31/18
