Answer 1

Answer:

(a) 4.63*10^-5

(b) 4.63*10^-3

(c) 2.3 × 10¹

(d) 1.23*10^7

Step-by-step explanation:

a) 463 × 10^-7

= (463)×10^-2 × 10^-5

= (463/10²) × 10^-5

= 4.63*10^-3

ii) 14.63 × 10^-7

= 14.63 × 10^-1 × 10^-6

= (14.63/10) × 10^-6

= 1.473 × 10^-6

b) 23 = 23×(10/10)

= (23/10) × 10¹

= 2.3 × 10¹

c ) 123 × 10^5

=( 123/100) × 100 × 10^5

= 1.23 × 10² × 10^5

= 1.23*10^7

i ) 1150 × 10²

= (1150/100)×100×10²

= 11.5 × 10² × 10²

= 11.5 × 10⁴
