Express your answer in scientific notation. 9.3 x 107 - 3.14 x 106 question 2 options: 8.1 x 107 8.1 x 106 8.98 x 107 8.98 x 106

Step-by-step explanation:

The given expression is

To solve this, we first need to have the like powers, that is, they must have the same exponent. To obtain such equivalence, we move the decimal point one spot to the right on the first term, that will decrease its exponent by one

Now, we extract common factors and subtract

However, the whole part of the decimal number of the scientific notation can only be between 0 and 10, and we have 89, to solve this problem, we move the decimal point one spot to the left

Therefore, the right answer is the third choice.

the expression (1.26)2t reveals the approximate rate of increases in the number of plants semiannually.

hope this : )
