expand pi((125-21sqrt(21))/3-2sqrt(21))

expand

π (\frac{125 - 21 21}{3} - 221)

\frac{125 π}{3} - 921 π

Solution steps

π (\frac{125 - 21 21}{3} - 221)

Apply the distributive law:

a (b - c) = ab - a c

a = π, b = \frac{125 - 21 21}{3}, c = 221

= π \frac{125 - 21 21}{3} - π 221

= π \frac{125 - 21 21}{3} - 221 π

Simplify

π \frac{125 - 21 21}{3} - 221 π : \frac{125 π}{3} - 921 π

= \frac{125 π}{3} - 921 π

- 2 a (2 sin (x) + x cos (x) + 2 b (2 cos (x) - x sin (x)))

f (- 2, - 1)

\frac{7 ( 38 - 2 b )}{5}

f (- 2, - 3)
