5*10^3 * 5*10^7= 5*5 *10^3*10^7=25*10^10
Generally u are allowed to leave it as it is but if no
25*10^10=25 * 10000000000 = 250000000000
Here u are!
Answer:
Step-by-step explanation:
if you know 50*4=200, you must also know that 50*10=500 and that 4*100=400 so 500*400= 50*10*4*100
multiplication is comutative so
50*4*10*100=200*1,000= 200, 000

Answer:
They both factored it correctly
Step-by-step explanation:
To find the one that was factored correctly, we expand the two of them and compare with 
.
Fernando
= 
=
Salma
= 
=
As we can see, they both factored it correctly.
If you want to increase something by 31% then...
100%+31%=131% or 1.31
you multiply it by 131% or 1.31. So for 429 grams...
429*1.31=561.99grams
If you increase 429 by 31%, you get 561.99 grams
Answer=561.99 grams
