Let's solve the equation step by step:

10000(1+х)^4 = 1.1(10000(1+20.15))10000(1+х)^4 = 1.1*(10000(1+0.3))10000(1+х)^4 = 1.1*(10000(1.3))10000(1+х)^4 = 1.1*1300010000(1+х)^4 = 14300(1+х)^4 = 1.43Take the fourth root of both sides: 1+х = 1.1х = 0.1

Therefore, the solution to the equation is х = 0.1.
