Solve -log(8 x (10^(-4)))

Evaluate

- lo g_{10} (8 x (1 0^{- 4}))

Calculate

- lo g_{10} (8 x \times 1 0^{- 4})

Multiply the numbers

More Steps

- lo g_{10} (\frac{1}{1250} x)

Rewrite the expression

- lo g_{10} (\frac{x}{1250})

Use lo g_{a} (\frac{x}{y}) = lo g_{a} (x) - lo g_{a} (y) to transform the expression

- (lo g_{10} (x) - lo g_{10} (1250))

Simplify the expression

More Steps

- (lo g_{10} (x) - (1 + 3 lo g_{10} (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

- (lo g_{10} (x) - 1 - 3 lo g_{10} (5))

Solution

- lo g_{10} (x) + 1 + 3 lo g_{10} (5)
