expand sqrt(7)(8-sqrt(13))

expand

7 (8 - 13)

87 - 91

Decimal Notation

11.62661 \dots

Solution steps

7 (8 - 13)

Apply the distributive law:

a (b - c) = ab - a c

7 (8 - 13) = 7 \cdot 8 - 713

= 7 \cdot 8 - 713

7 \cdot 8 - 713 = 87 - 91

= 87 - 91

\frac{1}{8} (arcsin (y) - \frac{1}{4} sin (4 arcsin (y)))

(cos^{2} (x) + sin^{2} (x))^{2}

(cos (θ) + i sin (θ))^{2} (1 + 2 cos (θ))

(3 x - 5 y = 4,) (3 x - 2 y = 12)

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