Express the product of 3.2 × 106 and 4.1 × 10–1 in the standard form.

Given that, to find the product of 3.2 × 106 and 4.1 × 10–1


Product of 3.2 × 106 and 4.1 × 10–1 = (3.2 × 106)( 4.1 × 10–1)


= (3.2 × 4.1) × 106 × 10-1


Using the law of exponent,


13.12 × 105


= 1.312 × 105 × 101


= 1.312 × 106


The product of 3.2 × 106 and 4.1 × 10–1 in the standard form is 1.312 × 106.
