Given that log 2 = x, log 3 = y and log 7= z, express the following expression in terms of x, y, and z: a) log 0.3
b) log 200

None of the options you showed are it.

Remember, you can do anything to an equation as long as you do it to both sidesminus 36 from both sides4.5(8-x)=66-2.5(3x+24)distribute36-4.5x=66-7.5x-60add like terms36-4.5x=-7.5x+6add 7.5x to both sides36+3x=6minus 36 from both sides3x=-30divide both sides by 3x=-10

X=-1 hope this
