Question
Calculate the value
−log10(3)+1+log10(5)
Alternative Form
≈1.221849
Evaluate
−log10(1006)
Cancel out the common factor 2
−log10(503)
Use loga(yx)=loga(x)−loga(y) to transform the expression
−(log10(3)−log10(50))
Simplify the expression
More Steps
Evaluate
log10(50)
Use loga(x×y)=loga(x)+loga(y) to transform the expression
log10(10)+log10(5)
Use logaan=n to simplify the expression
1+log10(5)
−(log10(3)−(1+log10(5)))
If a negative sign or a subtraction symbol appears outside parentheses, remove the parentheses and change the sign of every term within the parentheses
−(log10(3)−1−log10(5))
Solution
−log10(3)+1+log10(5)
