Question

0.4 × 0.04 × 0.005 by 0.1 × 10 × 0.001 - 1 by 2 + 1 by 5

Answer 1

Given:

0.4 × 0.04 × 0.005 by 0.1 × 10 × 0.001 - 1 by 2 + 1 by 5

To find:

0.4 × 0.04 × 0.005 by 0.1 × 10 × 0.001 - 1 by 2 + 1 by 5

Solution:

From given, we have,

0.4 × 0.04 × 0.005 by 0.1 × 10 × 0.001 - 1 by 2 + 1 by 5

= 4 × 10^-1 × 4 × 10^-2 × 5 × 10^-3 by 1 × 10^-1 × 10 × 1 × 10^-3 - 1 by 2 + 1 by 5

= (80  × 10^-6)/(10 × 10^-4) - 1/2 + 1/5

= 8 × 10^-2 - 1/2 + 1/5

= 0.08 - 0.5 + 0.2

= - 0.22

∴ 0.4 × 0.04 × 0.005 by 0.1 × 10 × 0.001 - 1 by 2 + 1 by 5 = -0.22
