Simplify this expression and put your final answer in Scientific Notation: 2.7×10^5/3.2×10^7 (4 points)
Step 1: ______the coefficients.
Step 2: ______to simplify the exponents.
Step 3: ______to change into Scientific Notation. < options: add to the exponents, subtract from the exponents
Step 4: ______is the simplified answer. < options: 0.844 * 10^2 , 0.844 * 10^-2 , 8.44 * 10^-3 , 8.44 * 10^12 , 8.44 * 10^-1
Step 1: Divide the coefficients 2.7/3.2 = 0.84375 (rounded to 5 decimal places)
Step 2: Subtract the exponents 5-7 = -2
Step 3: Change into Scientific Notation, 0.84375 * 10^-2
Step 4: 0.84375 * 10^-2
Therefore, the simplified answer is 8.4375 * 10^-1.
how to change step 3 to a scientific notation
To change step 3 into Scientific Notation, you need to express the result in the format a × 10^b, where 1 ≤ |a| < 10 and b is an integer.
Given the result from step 3 (0.84375 * 10^-2), you can rewrite it as 8.4375 * 10^-1 in Scientific Notation by moving the decimal one place to the left which increases the exponent by 1:
8.4375 * 10^-1
Therefore, after converting step 3 into Scientific Notation, the simplified answer is 8.4375 * 10^-1.
