Answer:Write in scientific notation, moving the decimal in the coefficient one place to the left, which adds 1 to the exponent value. I just took the test in ingenuity
Let's rewrite the numbers correctly: 3.2 × 10 ^ 4 3.6 × 10 ^ 2 Now let's do the multiplication step by step: Step 1: The step Kevin made: (3.2 * 3.6) * ((10 ^ 4) * (10 ^ 2)) 11.52 * (10 ^ (4 + 2)) 11.52 * 10 ^ 6 Step 2: Rewrite the expression: 11.52 * 1000000 Step 3: Roll the comma to the right: 11520000 Answer: the next step that Kevin should apply to his solution is: Step 2: Rewrite the expression: 11.52 * 1000000 Step 3: Roll the comma to the right: 11520000
-2/3 times -2. You change -2 into -2/1 so you can multiply numerator to numerator and denominator to denominator. You will get 4/3 (negatives cancel out)
