This week in math 10 with Mrs. Burton we started a new unit. We started learning abut exponents. The new thing I learned about this past week has been the BEDMAS laws. With exponents, we follow four main laws. The division law, multiplication law, zero law and power of power law. Each law eliminates a different part of the equation. The division law is when you subtract the powers the equation. For the division law to work the bases must ALL be the same. So for example, if you have 7 to the power of 5 divided by 7 to the power of 2, you would get 7 to the power of 3 as an answer. Now with the multiplication law the bases also must be the same but instead of subtracting like you would in the division law, now we add. So if you have 8 to the power of 3 and 8 to the power of 4 you would get 8 to the power of 7 as an answer. For the Zero law exponent law it ONLY works when the exponent in a equation is 0. When that is the case, no matter what the base is the number will always be whatever the coefficient is. If there is no coefficient given, we automatically know the answer is 1 since there is an invisible 1 in the coefficient spot. The last law kids the pp law also known as the power to power law. In this law, you will ALWAYS multiply. If you have (2 to the power of 3 ) to the power of 2 t would equal 2 to the power of six because you simply multiply 2 of what is inside the ( )’s.
