Answer 1

its either 9.6 x 1021 or 9.6x1022
hope this helps

Answer 2

9.6 ×
`10^(21) )`.

Explanation:

Given : Multiply
`(2.4 * 10^(14) ) * ( 4 *10^(7) )`.

To find : Express the answer in scientific notation.

Solution : We have given that

`(2.4 * 10^(14) ) * ( 4 *10^(7) )`.

Combine the like terms

(2.4 * 4 )(
`(10^(14) ) (10^(7) )`.

By the exponent same base rule : if the base of two exponent are same then exponent will be add.

9.6 ×
`10^(14 + 7) )`.

9.6 ×
`10^(21) )`.

Therefore, 9.6 ×
`10^(21) )`.
