Hello!

Answer:

$\Large \boxed{\sf 4.216 * 10^3}$

Step-by-step explanation:

Scientific notation is notation that makes it easy to express and compare very large or very small numbers.

It consists of expressing the number in the form
$\sf \pm a* 10^(n)$ , where:

$\sf \pm$ is called a sign

$\sf a$ is a decimal number in the interval (1; 10[ called mantissa

$\sf n$ is a relative integer called exponent

◼ The sign is positive because 4,216 is a positive number

◼ The decimal number in the interval (1; 10[ is 4.216 because
$\sf 1 \leq4.216 < 10$

◼ The exponent is 10³ because
$\sf 4,216 = 4.216 * 1000 = 4.216 * 10^3$

So we have:

$\boxed{\sf 4,216 = 4.216 * 10^3}$
