simplify log_{7}(8)+log_{7}(5)

simplify

lo g_{7} (8) + lo g_{7} (5)

lo g_{7} (40)

Decimal Notation

1.89570 \dots

Solution steps

lo g_{7} (8) + lo g_{7} (5)

Apply log rule:

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

lo g_{7} (8) + lo g_{7} (5) = lo g_{7} (8 \cdot 5)

= lo g_{7} (8 \cdot 5)

Multiply the numbers:

8 \cdot 5 = 40

= lo g_{7} (40)

2 lo g_{10} (x) - 4 lo g_{10} (x + 1) - 3 lo g_{10} (5 x) + \frac{1}{3} lo g_{10} (x - 1)

(2) lo g_{10} (3 x^{2}) - lo g_{10} (2 x^{2} - 1)

3 lo g_{5} (a) - lo g_{5} (b)

ln (\frac{t}{2 t + 3})
