Find (1.6 x 108)(5.8 x 106) (4 x 106) , expressed in scientific notation. a) 1.05 x 108 b) 2.32 x 108 c) 2.32 x 109 d) 9.28 x 108

(1.6 x 10^8)(5.8 x 10^6)

(4 x 10^6)

multiply the numbers and add the exponent for the numerator

(1.6 x 5.8) x 10^(8+6)

(4 x 10^6)

(9.28) x 10^(14)

(4 x 10^6)

divide the numbers and subtract the exponents for division

(9.28/4) x 10^(14-6)

2.32x 10^(8)

Choice B

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
