Answer 1

a.)0.00000865 = 865/100000000 = 865 × 1 / 100000000 = 8.65/100 × 1/100000000 = ${8.65 × 10^{-10.}}$

b.)0.00000052 = 52/100000000 = 5.2 /10 × 1/100000000 = ${5.2 × 10^{-9.}}$

c.)674000000 = 674 × 1000000 = 6.74 × 100 × 1000000 = ${6.74×10^8.}$

d.)5000000000 = 5 × 1000000000 = ${5×10^9.}$
