  • Mudathir azeez: log(b³) + log(b5) - log(b6)=log(64)
    Log(b3 .b5) - log(b6)=log(64)
    log(b8)-log(b6)=log(64)
    log(b8/b6)=log(64)
    log(b^(8-6))=log64
    b²=64
    b=√64
    b=8

3Log b+5Log b-6Log b = Log 64
Log b¤3+Logb¤5-Logb¤6 = Log 64
Log(b¤3+5/b¤6) = Log 64
Log b¤8-6 = Log 64
Log b¤2 = Log 64
b¤2 = 64
b=Square root(64)
b= 8

The answer is 8
