Question

What is (4x10^4)(2x10^3) in scientific notation?

Answer 1

• Given:

`(4 *10^(4) (2*10^(3) )`

Find the product in scientific notation.

• Step-by-step explanation:

The multiply numbers in scientific notation first multiply the numbers that are not powers of 10, then add the powers of ten):

`(4*10^(4) )(2*10^(3)) =(2*4)*10^(4+3) = 8*10^(7)`

Then the product is 8×10^7
