Find (1.6 x 108)(5.8 x 106) (4 x 106) , expressed in scientific notation
A) 1.05 * 10^8
B) 2.32 * 10^8
C) 2.32 * 10^9
D) 9.28 * 10^8

Answer 1

2.32 x 10^8

Explanation:

2.32 x 108

108 + 6 - 6 = 108

and

(1.6)(5.8)

(4)

=

9.28

4

= 2.32

thus,

2.32 x 108

Answer 2

we are given

`((1.6* 10^(8))(5.8* 10^(6)))/((4* 10^(6)))`

Since, we have to write this in scientific form

so, we will make all 10^x terms together

and all other terms together

so, we get

`=((1.6* 5.8) (10^(8)* 10^(6)))/((4* 10^(6)))`

we can multiply terms

`=((9.28) (10^(8+6)))/((4* 10^(6)))`

`=((9.28) )/(4) * 10^(8+6-6)`

`=2.32 * 10^(8)`

so, option-B...........Answer
