2. The 4 Step Approach
Make sure that the bases are the same. To multiply - add the exponents and multiply the coefficients - and to divide - subtract the exponents and divide the coefficients - 3x^25x^3=15x^5 and 15x^6/3x^2=5x^4
To add and subtract exponents - both the base and the power must be the same. If they are - just add or subtract as you normally would. So - 3x^2+5x^2=8x^2
