Ka mau nanya 1. 40 x 10^-3 - 0.05 x 10^-3 2. 55x 10^-3 - 0,08 x 10^-3 4. 80 x 10^-3 - 0,11 x 10^-3 5. 95 x 10^-3 - 0,745 x 10^-3

nomor 1
[tex](40 \times {10}^{ - 3}) - (0.05 \times {10}^{ - 3}) \\ = (40 - 0.05) ( {10}^{ - 3} ) \\ = 39.05 \times {10}^{ - 3} [/tex]

nomor 2
[tex]55 \times {10}^{ - 3} - 0.08 \times {10}^{ - 3} \\ = (55 - 0.08) \times {10}^{ - 3} \\ = 54.92 \times {10}^{ - 3} [/tex]

nomor 3
[tex]80 \times {10}^{ - 3} - 0.11 \times {10}^{ - 3} \\ = (80 - 0.11) \times {10}^{ - 3} \\ = 79.89 \times {10}^{ - 3} [/tex]

nomor 4
[tex]95 \times {10}^{ - 3} - 0.745 \times {10}^{ - 3} \\ = (95 - 0.745) \times {10}^{ - 3} \\ = 94.255 \times {10}^{ - 3} [/tex]

Syukron
semoga terbantu
maaf kalo salah
