Answer 1

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

Answer 2

3.712 x 10^8

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'sur answer
