simplify log_{7}(9)+log_{7}(8)

simplify

lo g_{7} (9) + lo g_{7} (8)

lo g_{7} (72)

Decimal Notation

2.19777 \dots

Solution steps

lo g_{7} (9) + lo g_{7} (8)

Apply log rule:

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

lo g_{7} (9) + lo g_{7} (8) = lo g_{7} (9 \cdot 8)

= lo g_{7} (9 \cdot 8)

Multiply the numbers:

9 \cdot 8 = 72

= lo g_{7} (72)

f (x) = lo g_{10} (2 x) - lo g_{10} (8 x^{3})

ln (x y z^{6})

\frac{ln ( 2 )}{ln ( 2 ) - 2 ln ( 3 )}

lo g_{10} ((x + y)^{3}) - lo g_{10} (x + y)

lo g_{4} (x^{2} - 1) - 5 lo g_{4} (x + 1)
