Answer

= 5\hat{i} - \hat{j} - 9\hat{k}

Steps

Step 1 :The subtraction of two vectors is done component-wise. Thus, the difference AB can be calculated as follows:

Step 2 :AB=(3i^+2j^4k^)(2i^+3j^+5k^)

Step 3 := (3 - (-2))\hat{i} + (2 - 3)\hat{j} + (-4 - 5)\hat{k}

Step 4 := 5\hat{i} - \hat{j} - 9\hat{k}
