Jawaban :
1) 2,34 x 10⁵ + 1,22 x 10⁶
= (2,34 x 100.000) + (1,22 x 1.000.000)
= ( 234.000 ) + ( 1.220.000 )
= 1.454.000
2) 3,12 x 10⁸ - 0,15 x 10⁷
= (3,12 x 100.000.000) - (0,15 x 10.000.000)1
= 312.000.000 - 1.500.000
= 310.500.000
3) 1,32 x 10^-3 + 2,14 x 10^-2
= (1,32 x 10^-3 + 2,14 x 10^-2)
= (1,32 x 0,001) + (2,14 x 0,01)
= 0,00132 + 0,0214
= 0,02272
4) 1,45 x 10^-5 - 0,23 x 10^-6
= (1,45 x 10^-5) - 0,23 x 10^-6
= (1,45 x 0,00001) - ( 0,23 x 0,000001)
= 0,0000145 - 0,0000023
= 0,0000122
Tolong sambil dipelajari yaa, maaf kalau salah.
