a. 3.971 x 107 + 1.98 x 104;
b. 1.05 x 104 - 9.7 x 10-5;
c. 4.11 x 10-3 + 8.1 104;
d. 2.12 x 106 - 3.5 x 105.​

Answer 1

Answer:

This mathematical problem will be solved using BODMAS. BODMAS is an acronyms of Bracket, orders, division, multiplication, addition and subtraction.

For Question A:

3.971 x 107 + 1.98 x 104;

(3.971 x 107) + (1.98 x 104)

(424.897) + (295.92)

630.817

thus, the answer is 630.817

For Question B:

1.05 x 104 - 9.7 x 10-5:

(1.05 x 104) - (9.7 x 10-5)

(109.2) - (92)

17.2

thus, the answer is 17.2

For Question C:

The third question is not clear enough, but i want to assumed you mean

4.11 X 10-3 +8.1 x 104:

(4.11 x 10-3) - (8.1 x 104)

(3.81) x (842.4)

3209.544

thus, the answer is 3209.544

For Question D:

2.12 x 106 - 3.5 x 105

(2.12 x 106) - (3.5 x 105)​

(224.72) - (367.5)

-142.78

thus, the answer is -142.78
