Question

Yg nomer 2 gimana ya? bantu jawab yaa plisssssss

Answer 1

2) a. (7^3)^x-1 = (7^-1)^4x-3
        3(x-1) = -1(4x-3)
        3x-3 = -4x+3
        7x = 6
        x = 6/7
    b. ((3^2)^x+2)^2 dibagi (3^3)^x = 3^4
        (2(x+2))2 dibagi 3x = 4
        (2x+4)2 dibagi 3x = 4
        4x+8 = 4 kali 3x
        4x+8 = 12x
        -8x = -8
        x = 1

semoga jawabanku bener yha
