Evaluate the expression. express the result in scientific notation. (9.08 × 106) – (2.25 × 105)

Step-by-step explanation:

Scientific notation has the form:

Where "a" is a number between 1 and 10 but less than 10 and "n" is a integer.

To make the subtraction, the bases must have the same exponent.

Then you can move the decimal point of one place to the left, then:

Now you can make the subtraction. Then you get:

2nd one in the first row is correct

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point
