In scientific notation, (6.2 x 10^4) x (3.3 x 10^2 ) equals ____________________.

Respuesta :

you will get 20460000 as your answer which is broken down into, 2.046 x 10^7 as your number has to be between 1-10.

For this case we have the following multiplication:

[tex] (6.2 * 10 ^ 4) * (3.3 * 10 ^ 2)
[/tex]

For associative property, we can rewrite the expression as:

[tex] (6.2 * 3.3) * (10 ^ 4 * 10 ^ 2)
[/tex]

Then, by properties of exponents we have:

In the multiplication, if we have the same base, the exponents are added.

Therefore, by rewriting the expression we have:

[tex] (6.2 * 3.3) * (10 ^{4 + 2})
[/tex]

Finally:

[tex] (20.46) * (10 ^ 6)
[/tex]

Then, we rewrite the result correctly in scientific notation.

To do this, we move the point one space to the left and increase the degree of the exponent one unit:

[tex] 2.046 * 10 ^ 7
[/tex]

Answer:

In scientific notation, [tex] (6.2 * 10 ^ 4) * (3.3 * 10 ^ 2) [/tex] equals[tex] 2.046 * 10 ^ 7 [/tex]
