+163 What would the answer be to -
5 x 4 x 103
(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 x103 or 2 x 104)
PLEASE HELP
+37159 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
+66 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
