simplify i^{131}+3i^{219}-21i^{191}

simplify

i^{131} + 3 i^{219} - 21 i^{191}

17 i

Solution steps

i^{131} + 3 i^{219} - 21 i^{191}

i^{131} = - i

3 i^{219} = - 3 i

21 i^{191} = - 21 i

= - i - 3 i - (- 21 i)

Apply rule:

a - (- b) = a + b

- 3 i - (- 21 i) = - 3 i + 21 i

= - i - 3 i + 21 i

Add similar elements:

- i - 3 i + 21 i = 17 i

= 17 i

\frac{csc ( x )}{tan ( x ) + cot ( x )}

3 (x + 4) (x - 5)

6 a + 3 b - 7 c - (2 a + 5 b) + 4 c

\frac{10000}{4 π \cdot ( 7.5 \cdot 1 0 ^{- 3} ) ^{2}}

\frac{22}{52}
