To simplify the given logarithmic expression, we can use the properties of logarithms. Specifically, we can use the power rule, which states that alogbc=logb(ca), and the product and quotient rules, which state that logbm+logbn=logb(mn) and logbm−logbn=logb(nm), respectively. Applying these rules will allow us to combine the terms into a single logarithm.
Step 1: Apply the Power Rule of Logarithms
The given expression is 4log5x+3log5y−2log5z. Using the power rule of logarithms, which states that alogbc=logb(ca), we can rewrite each term as:
4log5x=log5(x4)
3log5y=log5(y3)
−2log5z=log5(z−2)
Step 2: Apply the Product and Quotient Rules of Logarithms
Next, we use the product rule logbm+logbn=logb(mn) and the quotient rule logbm−logbn=logb(nm) to combine the terms:
log5(x4)+log5(y3)−log5(z−2)=log5(z2x4⋅y3)
