Answer:

0.8

Step-by-step explanation:

  • [tex](4*10^-^1)+(4*10^-^1)[/tex]
  • [tex](4*0.1)+(4*0.1)[/tex]
  • [tex]0.4 + 0.4[/tex]
  • [tex]0.8[/tex]

Answer:

  • Standard form : N × 10ⁿ

[tex] \longmapsto (4 \times {10}^{ - 1} ) + (4 \times {10}^{ - 1} ) \\ = \frac{4}{10} + \frac{4}{10} \\ = \frac{(4 + 4)}{10} \\ = \frac{8}{10} \\ = \boxed{8 \times {10}^{ - 1} }[/tex]

  • 8×10^(-1) (in standard form) is the right answer.
