step by step please!!

Answer 1

no, i want it answered in scientific form

Answer 2

To subtract these two numbers, you first need to convert them into the same exponent format.

Step 1: Convert 3.006 x 10^1 to scientific notation:
3.006 x 10^1 = 30.06

Step 2: Convert 3.9 x 10^-1 to scientific notation:
3.9 x 10^-1 = 0.39

Now that both numbers are in decimal format, you can subtract them:

30.06 - 0.39 = 29.67

Therefore, the subtraction of 3.006 x 10^1 and 3.9 x 10^-1 is 29.67.

Answer 3

Apologies for the confusion. Let's write the answer in scientific notation.

Step 1: Rewrite the numbers in standard decimal notation:
- 3.006 x 10^1 becomes 30.06
- 3.9 x 10^-1 becomes 0.39 (since 10^-1 means to move the decimal point one place to the left)

Step 2: Subtract the two decimal numbers:
30.06 - 0.39 = 29.67

Step 3: Write the answer in scientific notation:
29.67 can be written as 2.967 x 10^1

So, the result of 3.006 x 10^1 - 3.9 x 10^-1 is 2.967 x 10^1.
