Question

Work out (8 x 10^-3) * (2 x 10^-4)
Give your answer in standard form.

Answer 1

(8×10^-3)( 2×10^-4)

=(8)(2)× 10^-3× 10^-4

=16× 10^-7

Answer 2

The result of the expression is 0.0000016

Using the expression given :

• 
  `(8 * 10^(-3)) * (2 * 10^(-4))`

`(8 * 10^(-3)) = 8 × 0.001 = 0.008`

`(2 * 10^(-4)) = 2 × 0.0001 = 0.0002`

Multiply :

0.008 * 0.0002 = 0.0000016

Hence, the result of the expression is 0.0000016
