Which shows the expression below in simplified form? (2.4 × 1018) + (3.4 × 1015)
RUDIKE [14]

Answer: 5894.2

Step-by-step explanation:

You'll want to follow PEMDAS to simplify this expression.

1.) P - Parentheses

2.) E - Exponents

3.) M - Multiplication

4.) D - Division

5.) A - Addition

6.) S - Subtraction

We'll start with what's inside the parentheses:

(2.4 × 1018) + (3.4 × 1015)

(2,443.2) + (3,451)

Now all you have to do is add the values together to get your answer!

2,443.2 + 3,451

Nesterboy [21]

Answer:

I don't have an answer for this, but I can at least help you with calculating speed, distance, and time

Step-by-step explanation:

My teachers taught me about the magic pyramid. Distance is above speed and time. Speed is to the left of time and time is to the right of speed.

Distance = speed x time

Speed = distance/time

Time = distance/speed

I may not have an answer to your question, but hopefully, this helps you.
