expand

3 (7 - 25)

73 - 215

Decimal Notation

4.37838 \dots

Solution steps

3 (7 - 25)

Apply the distributive law:

a (b - c) = ab - a c

3 (7 - 25) = 3 \cdot 7 - 3 \cdot 25

= 3 \cdot 7 - 3 \cdot 25

3 \cdot 7 - 3 \cdot 25 = 73 - 215

= 73 - 215

lo g_{10} (x)

(x + 3) (x - 3)

(cos (t) + 5 e^{4 t})^{3}

(x + 25)^{2}

(cos (x) + i sin (x))^{3}
