simplify log_{4}(x-7)+log_{4}(x-7)-1

simplify

lo g_{4} (x - 7) + lo g_{4} (x - 7) - 1

lo g_{2} (x - 7) - 1

Solution steps

lo g_{4} (x - 7) + lo g_{4} (x - 7) - 1

Add similar elements:

lo g_{4} (x - 7) + lo g_{4} (x - 7) = 2 lo g_{4} (x - 7)

= 2 lo g_{4} (x - 7) - 1

Simplify

2 lo g_{4} (x - 7) : lo g_{2} (x - 7)

= lo g_{2} (x - 7) - 1

2 x^{2} - 9 x^{5} - 3 x

1 + 12 x^{2} \cdot y - 6 x y - 8 x^{3} \cdot y^{3}

(1.1 m - 0.4) (1.1 m + 0.4)

(22 a + 3 b + 4 c)^{3}

x^{2} - 2 x y
