Answer:
0.000056
Step-by-step explanation:
[tex] \\ 6 \times {10}^{ - 5 } - 4 \times {10}^{ - 6} [/tex]
[tex] \\ \longrightarrow6 \times \frac{1}{ {10}^{5} } - 4 \times \frac{1}{ {10}^{6} } [/tex]
[tex] \\ \longmapsto6 \times \frac{1}{ 100000 } - 4 \times \frac{1}{1000000}[/tex]
[tex] \\ \longmapsto0.00006 - 0.000004[/tex]
[tex] \\ \longmapsto0.000056[/tex]
