simplify log_{4}(8)+log_{4}(5)

simplify

lo g_{4} (8) + lo g_{4} (5)

lo g_{4} (40)

Decimal Notation

2.66096 \dots

Solution steps

lo g_{4} (8) + lo g_{4} (5)

Apply log rule:

lo g_{a} (x) + lo g_{a} (y) = lo g_{a} (x y)

lo g_{4} (8) + lo g_{4} (5) = lo g_{4} (8 \cdot 5)

= lo g_{4} (8 \cdot 5)

Multiply the numbers:

8 \cdot 5 = 40

= lo g_{4} (40)

- 29 = 5 x + 6 - 12 x

x^{2} - x - 1

\frac{- 8}{- 4}

\frac{x ^{- 4}}{x ^{- 8}}

x^{2} - 12 x + 63 = 0
