Nomor 1

$displaystyle ttsum_{t=1}^{5} {t}^{2}$

$tt = {1}^{2} + {2}^{2} + {3}^{2} + {4}^{2} + {5}^{2}$

$tt = underline{1 + 4 }+ underline{ 9 + 16} + 25$

$tt = underline{5 + 25 }+ 2$

$tt = 30 + 25$

$tt = bold{ 55}$

$\$

Nomor 2

$displaystyle ttsum_{n=0}^{7} (2n + 1)$

$small{ tt = (2(0) + 1) + (2(1) + 1) + (2(2) + 1) + (2(3) + 1) + (2(4) + 1) + (2(5) + 1) + (2(6) + 1) + (2(7) + 1)}$

$tt = underline{1 + 3}+ underline{ 5 + 7 }+ underline{ 9 + 11 }+ underline{13 + 15}$

$tt = underline{ 4 + 12 }+ underline{20 + 28 }$

$tt = 16 + 48$

$tt = 64$

$\$

Nomor 3

$displaystyle ttsum_{n = 2}^{6} {2}^{n - 2}$

$tt = {2}^{2 - 2} + {2}^{3 - 2} + {2}^{4 - 2} + {2}^{5 - 2} + {2}^{6 - 2}$

$tt = {2}^{0} + {2}^{1} + {2}^{2} + {2}^{3} + {2}^{4}$

$tt = underline{1 + 2 }+ underline{4 + 8 }+ 16$

$tt = underline{ 3 + 12 }+ 16$

$tt = 15 + 16$

$tt = 31$

$\$

Nomor 4

$displaystyle ttsum_{i=1}^{11} {( - 1)}^{i}$

$tinytt = {( - 1)}^{1} + {( - 1)}^{2} + {( - 1)}^{3} + {( - 1)}^{4} + {( - 1)}^{5} + {( - 1)}^{6} + {( - 1)}^{7} + {( - 1)}^{8} + {( - 1)}^{9} + {( - 1)}^{10} + {( - 1)}^{11}$

$tiny tt = underline{ ( - 1) + 1 }+ underline{( - 1) + 1 }+ underline{( - 1) + 1 }+ underline{( - 1) + 1 }+ underline{( - 1) + 1 }+ ( - 1)$

$tiny tt = 0 + 0 + 0 + 0 + 0 + ( - 1)$

$tiny tt = - 1$

$\$

Nomor 5

$displaystyle ttsum_{a= - 2}^{4} begin{pmatrix} frac{a}{a + 6} end{pmatrix}$

$tinytt = ( frac{ - 2}{ - 2 + 6} ) + ( frac{ - 1}{ - 1 + 6} ) + ( frac{0}{0 + 6} ) + ( frac{1}{1 + 6} ) + ( frac{2}{2 + 6} ) + ( frac{3}{3 + 6} ) + ( frac{4}{4 + 6} )$

$tt = frac{ - 2}{4} + frac{ - 3}{5} + 0 + frac{1}{7} + frac{2}{8} + frac{3}{9} + frac{4}{10}$

$tt = frac{ underline{- 1260 +( - 162)}+ underline{360 + 630}+ underline{840 + 1008} }{2520}$

$tt = frac{ - 1422 +990 +1848}{2520}$

$tt = frac{ - 432 + 1848}{2520}$

$tt = frac{1416}{2520}$

$tt = frac{177}{315}$

$\$

Nomor 6

$displaystyle ttsum_{n = 3}^{6} frac{n + 1}{n - 2}$

$tt = frac{3 + 1}{3 - 2} + frac{4 + 1}{4 - 2} + frac{5 + 1}{5 - 2} + frac{6 + 1}{6 - 2}$

$tt = frac{4}{1} + frac{5}{3} + frac{6}{3} + frac{7}{4}$

$tt = 4 + frac{5}{3} + 2 + frac{7}{4}$

$tt = (4 + 2) + ( frac{5}{3} + frac{7}{4} )$

$tt = 6 + ( frac{20 + 21}{12} )$

$tt = 6 + frac{41}{12}$

$tt = 6 +3 frac{5}{12}$

$tt = 9 frac{5}{12}$
