What is the value of ( 8 x 10 to the 3rd power ) + ( 4 x 10 to the 2nd power )

Answer 1

Hello!

Answer:

`\Large \boxed{\sf 8400~ or ~8.4 * 10^3 }`

Explanation:

We want the value of:

`\sf (8 * 10^3) + (4 * 10^2)`

Let's simplify this expression:

`\sf (8 * 10^3) + (4 * 10^2)\\\\= (8 * 10* 10* 10) + (4 * 10* 10)\\\\= (8 * 1000) + (4 * 100)\\\\= 8000 + 400\\\\\boxed{\sf = 8400 = 8.4* 10^3 }`
