Q. Express the given expression as an integer or as a fraction in simplest form.(10log10+log7)Answer:
Understand Properties of Logarithms: Understand the properties of logarithms.The expression (10log10+log7) can be simplified using the properties of logarithms. Specifically, the property that states logb(m)+logb(n)=logb(m∗n) can be applied here.
Apply Logarithm Property: Apply the logarithm property to combine the logarithms.Using the property from Step 1, we can combine the logarithms inside the exponent:10log10+log7=10log(10×7)
Simplify Expression Inside Logarithm: Simplify the expression inside the logarithm.Now we simplify the multiplication inside the logarithm:10log(10×7)=10log(70)
Apply Definition of Logarithm: Apply the definition of a logarithm. The definition of a logarithm states that if bx=y, then logb(y)=x. Applying this definition to our expression, we get: 10log(70)=70
