Question

Evaluate. Express the answer in scientific notation and decimal notation. 4x1010 5x1014

Answer 1

Answer:

1.$40000000000$
2.$500000000000000$
(In case you were asking me to multiply, 20 × 10^24)

Step-by-step explanation:

Given the following questions:
$4\times10^{10}$
$5\times10^{14}$

In order to find the answers, we take note on how the exponents are positive. We also need to remember how integers always have invisible decimal points.

Question one:

$4\times10^{10}$
$4\times10^{10} =4.0.0.0.0.0.0.0.0.0.0.$
$4.0.0.0.0.0.0.0.0.0.0.=40000000000$
$40000000000$

Question two:

$5\times10^{14}$
$5\times10^{14}=5.0.0.0.0.0.0.0.0.0.0.0.0.0.0.$
$5.0.0.0.0.0.0.0.0.0.0.0.0.0.0.=500000000000000$
$500000000000000$

In case you were asking me to multiply:

$40000000000\times500000000000000=20000000000000000000000000$
$20000000000000000000000000=20\times10^{24}$
$20\times10^{24}$

Hope this helps.
