Scientific notation of (4.5+ 17) x 104 -1.5 x 104

4.5× 104 + 1.7× 105. Firstly, we need to ensure that both exponents have the same value. Thus, we need to change the value of 1.7 x 105 to 17 x 104. If both already had the same exponential value, you can neglect this step. 4.5× 104+ 17 × 104. Now, we will take exponentials common and add the decimal values. (4.5+ 17) × 104 | 21.5 × 104. Similar steps are taken for the subtraction phase we just need to retrace our steps and find differences rather than sums. These lessons and worksheets show you how to perform sums and differences with values that are in scientific notation.

Explanation:

I think it helps you

explanation: it gains negative electrons, therefore becoming negatively charged. as charge cannot be created, nor destroyed, only transferred, this leaves the wool positive. now that they have opposite charges, the two items attract.
