We need to add 1.45 x 10^8 and 3.9 x 10^7.
Please see..
We have given numbers in scientific form.
<em>We can't add the decimal numbers in front, because those numbers are being multiplied with 10 exponents and the exponents of 10's are not same.</em>
<em>So, we always convert the exponents of 10 as same.</em>
<em>1.45 x 10^8 could be converted to 14.5 x 10^7 to get exponent of 10 as 7 as other number 3.9 x 10^7 also has exponent of 10 as 7.</em>
<em>After this step we can just add the 14.5 and 3.9 and put × 10^7 with it.</em>
So, first correct step is:

2. Convert 1.45 x 108 to 14.5 x 107.</h3>
Answer:
Two rational roots: 1 and -1
Step-by-step explanation:
See the images for an explanation!
Given data:
The first equation is 3j +14=-5z.
The second equation is -10j=5z .
Add both the equations.

Substitute 2 for j in the first equation.

Thus, the value of j is 2 and z is -4.
