Solution steps

7 - lo g_{10} (7 a)

Simplify

lo g_{10} (7 a) : lo g_{10} (7) + lo g_{10} (a)

= 7 - (lo g_{10} (7) + lo g_{10} (a))

Apply the distributive law:

- (a + b) = - a - b

- (lo g_{10} (7) + lo g_{10} (a)) = - lo g_{10} (7) - lo g_{10} (a)

= 7 - lo g_{10} (7) - lo g_{10} (a)

(x + 1) (x + 2) (x + 3) (x + 4) - 3

1 + 2 \frac{b}{3} + \frac{b ^{2}}{9}

(\frac{x}{4 - 2 y})^{3}

w^{3} - 6 w - 9

(x + y)^{3} - x^{3} - y^{3}
