Step-by-step explanation:
a
[tex]9 \times {10}^{ - 7} = \frac{9}{10000000} = 0.0000009[/tex]
b
[tex]6.130 \times {10}^{ 9} = 6.13 \times {10}^{9} = 6130000000[/tex]
c
[tex]1 \times {10}^{15} = 1000000000000000[/tex]
d
[tex]1 \times {10}^{ - 5} = \frac{1}{100000} = 0.00001[/tex]
e
[tex] {10}^{ - 7 } = 1 \times {10}^{ - 7} = \frac{1}{10000000} = \\ = 0.0000001[/tex]
