SOAL 1
Dik :
x = 13²
y = √25 + √36
z = 2² + √100 + √49
Dit :
9x + 10x - 6y + 3y - 9z + 5z
Dij :
9x
= 9(13²)
= 9(169)
= 1.521
10x
= 10(13²)
= 10(169)
= 1.290
6y
= 6(√25 + √36)
= 6(√5² + √6²)
= 6(5 + 6)
= 6(11)
= 66
3y
= 3(√25 + √36)
= 3(√5² + √6²)
= 3(5 + 6)
= 3(11)
= 33
9z
= 9(2² + √100 + √49)
= 9(4 + √10² + √7²)
= 9(4 + 10 + 7)
= 9(4 + 17)
= 9(21)
= 189
5z
= 5(2² + √100 + √49)
= 5(4 + √10² + √7²)
= 5(4 + 10 + 7)
= 5(4 + 17)
= 5(21)
= 105
9x + 10x - 6y + 3y - 9z + 5z
= 1.521 + 1.690 - 66 + 33 - 189 + 105
= 3.211 - 33 - 84
= 3.211 - 117
= 3.094
UwU
x = 13²
= 13 × 13
= 169
y = √25 + √36
= 5 + 6
= 11
z = 2² + √100 + √49
= 4 + 10 + 7
= 14 + 7
= 21
Cara 1
9x + 10x - 6y + 3y - 9z + 5z
= 9(169) + 10(169) - 6(11) + 3(11) - 9(21) + 5(21)
= 1.521 + 1.690 - 66 + 33 - 189 + 105
= 3.211 - 66 + 33 - 189 + 105
= 3.145 + 33 - 189 + 105
= 3.178 - 189 + 105
= 2.989 + 105
= 3.094
Cara 2
9x + 10x - 6y + 3y - 9z + 5z
= (9x + 10x) + (-6y + 3y) + (-9z + 5z)
= 19x + (-3y) + (-4z)
= 19x - 3y - 4z
= 19(169) - 3(11) - 4(21)
= 3.211 - 33 - 84
= 3.178 - 84
= 3.094
