Answer 1

The simplified mathematical expressions with the first factor to the nearest tenth are:

7.8 x 10

3.3 x $10^{3}$

2.1 x $10^{-3}$

3.7

What are the simplified mathematical expressions ?

Scientific notation is used to simplify large numbers in smaller numbers.  In order to write a number in scientific notation , the number is written as a decimal number, between 1 and 10 and multiplied by a power of 10.

(8.6 x $10^{7}$) . (9.1 x $10^{-8}$)

= (8.6 x 9.1) x $10^{7 - 8}$

= 78.26 x$10^{-1}$

= 7.8 x 10

(6.9 x $10^{5}$) . (4.8 x $10^{-3}$)

= 33.12 x $10^{5 - 3}$

3.3 x $10^{3}$

(3.7 x $10^{2}$) . (4.6 x $10^{-3}$) ÷ (1.4 x $10^{-6}$) . (5.7 x $10^{8}$)

= 1.7 x 10 ÷ 8 x10²

0.21 x $10^{-2}$

2.1 x $10^{-3}$

(3.1 x $10^{5}$) . (5.3 x $10^{-9}$) ÷ (7.3 x $10^{2}$) . (6.1 x $10^{-7}$) = 3.7
