<h3>What is scientific notation?</h3>
Scientific notation is simply a way of expressing numbers that are too large or small to be written in decimal form.
It may be referred to as standard index form or scientific form.
From the information given, we have;
a. 0. 000003 is written in standard form as;
= 3 × 10^-6 × 3 × 10^6
= 3 × 10^-6 + 3
= 3 × 10^0
= 3
b. 56, 000, 000. 00 is written in standard form as;
= 5. 6 × 10^7 × 6 × 10^-7
= 33. 6 × 10^7 -7
= 33. 6 × 10^0
= 33. 6
c. 8. 0 × 10^-3 × 7. 2 × 10^5
= 57. 6 × 10^-3 + 5
= 57. 6 × 10^2
d. 4. 0 × 10^-3 × 4. 0 × 10^-4
= 4. 0 ^ -3 +(-4)
= 4. 0 × 10^-7
e. 7. 0 × 10^3 × 7. 0 × 10^4
= 7. 0 × 10^ 3-4
= 7. 0 × 10^-1
Thus, scientific notation is also referred to as standard form.

Answer:
Step-by-step explanation:
10m-2/5=9 and 3/5
10m-2/5=9.6 (where 9 and 3/5 is equal to 9.6)
50m-2=48 (i multiplied 10m by 5 and 9.6 by 5)
50m=50 ( i added 2 to both sides)
m=1 ( i divided by 50 to both sides to find m)
Answer:
Option D is correct
Step-by-step explanation:
From the question, we have:
Required
The tree diagram
The selection process is as follows:
-- i.e. we write sack 2 as a subset of 1
-- i.e. we write sack 3 as a subset of 2
<em>The only tree diagram that illustrates this is: option D</em>
