Subtract 5.8 × 10-3 from 3.5 × 10-2 and express result in scientific

1.	Subtract 5.8 × 10-3 from 3.5 × 10-2 and express result in scientific notation.
Answer» To perform subtraction operation, first the numbers are written in such a way that they have the same exponent. Then subtraction of coefficients can be done. (3.5 × 10^-2)- (5.8 × 10^-3) = (3.5 × 10^-2) – (0.58 × 10^-2) = (3.5 – 0.58) × 10^-2 = 2.92 × 10^-2

Answer»

To perform subtraction operation, first the numbers are written in such a way that they have the same exponent. Then subtraction of coefficients can be done.

(3.5 × 10^-2)- (5.8 × 10^-3)

= (3.5 × 10^-2) – (0.58 × 10^-2)

= (3.5 – 0.58) × 10^-2

= 2.92 × 10^-2
