What would the answer be to -

5 x 4 x 10^{3}

(I am confused to whether you do 5 x 4 first or you work out the whole answer and then the standard form)

( Either 9 x10^{3} or 2 x 10^{4})

PLEASE HELP

5 x 4 x 10^3 = 5 x 4 x 1000 you can do the multiplication in any order , the result will be the same

20,000 or 2 x 10^4

Use PEMDAS (also known as PEDMAS, they stand for the same thing)

**Parentheses**

**Exponents**

**Division and Multiplication from left to right**

**Addition and Subtraction from left to right**

Using this,

5*4*10^3

5*4*1000

20*1000

20000

Just saying there is a big probability that I am wrong, but..

5x4=20

10 cubed =1,000

20x 1,000=20,000

P.S soz if it's wrong
