Question

0.3485 = -----

• A. 3 x 10¹ + 4 x 10² + 8 x 10³ + 5 x 10⁴
• B. 3 x 10⁻¹ + 4 x 10⁻² + 8 x 10⁻³ + 5 x 10⁻⁴
• C. 3 x 10 + 4 x 10⁻² + 8 x 10⁻³ + 5 x 10⁻⁴
• D. 3 x 10⁻¹ + 4 x 10² + 8 x 10⁻³ + 5 x 10⁻⁴

Answer 1

Answer:

B. 3 x 10⁻¹ + 4 x 10⁻² + 8 x 10⁻³ + 5 x 10⁻⁴

3 x 10¹ + 4 x 10² + 8 x 10³ + 5 x 10⁴

= 3 x 10¹ + 4 x 10² + 8 x 10³ + 5 x 10⁴

= 30 + 400+ 8000 + 50000

= 58430

3 x 10^-1 + 4 x 10^-2 + 8 x 10^-3 + 5 x 10^-4

= 3 x 10^-1 + 4 x 10^-2 + 8 x 10^-3 + 5 x 10^-4

= 0.3 + 0.04 + 0.008 + 0.0005

= 0.3485

3 x 10 + 4 x 10^-2 + 8 x 10^-3 + 5 x 10^-4

= 3 x 10 + 4 x 10^-2 + 8 x 10^-3 + 5 x 10^-4

= 30 + 0.04 + 0.008 + 0.0005

= 30.0485

3 x 10^-1 + 4 x 10² + 8 x 10^-3 + 5 x 10^-4

= 3 x 10^-1 + 4 x 10² + 8 x 10^-3 + 5 x 10^-4

= 0.3 + 400 + 0.008 + 0.0005

= 400.3085
