Answer:
3.712 x 10^8
Step-by-step explanation:
use the commutative property to reorder the terms
(5.8x 6.4) x (10^5 x 10^2)
multiply 5.8 x 6.4 = 37.12
add 5+2=8
37.12 x 10^7
write the number in scientific notation
3.712 x 10^8
that's ur answer
Answer: 5.8 x 10^5 =
6.4 x 10^2 =
Step-by-step explanation:
There is 5 10's because number of exponents are 5
so you multiply 5.8 by 10 10 10 10 10
The other is 6.4
multiply that by 10 10
But you can't multiply by all of that with one constant
So you answer the first one 10 x 10 x 10 x 10 x 10 = 100000
the other is 100
So now you multiply 5.8 by 100000
And multiply 6.4 by 100
