* LAWS OF EXPONENTS ** RECAP *** BASE This is the number to be multiplied to itself *** EXPONENT this tells us the nuumber of times that the base will be used as a factor *** POWER Collective term for base and exponent ** CONTENT *** PRODUCT RULE same base but add the exponents, just add the goddamn exponents, the base means nothing to you here. FORMULA: a^m . a^n = a^m+n EXAMPLE: 3^5 . 3^7 = 3^7+5 (3^12) if its different bases, you cant add them, you need to copy the two different bases, thex product rule only applies in situations where the base is the same Also, if they're variables, dont put the sign, but they're constants, please do so: a^1 . b^1 = a^1 b^1 (FOR VARIABLES) 8^5 . 6^6 = 8^5 . 6^6 if you get into a situation like this below this text 6x^-4vc^5 . -4x^2v^7cd 1. first find the similar variables and group them, this is kinda the opposite of addition of polynomials which is tackled in a previous lecture (ref. L23GPMTH.org) v . v^7 = v^8 x^4 . x^2 = x^6 c^5 . c = c^6 addem da variables and exponents man 2. after that, multiple the constants and dont do anything with the variables 6 . -4 = -24d (d is a variable that so happens to be in the equation) 3. combine them -24dv^8c^6x^6 *** QUOTIENT RULE If you are dividing powers with the same base, copy the base and subtract the exponents 9^6 --- = 9^6-4 (9^2) 9^4 Always make sure numerator's exponent goes first, if the numerator is smaller than the denominator's exponent, still subtract, it will give you a negative output though. a^5 --- = a^5-7 (a^-2) a^7 negative exponents will be considered.. for now :)) if there are different bases, dont even think of trying to subtract them x^5 --- = no. you cant b^4 if you cant divide the denominator, you can do simpliest form [27]ac^5 ------ [18]bc^4 *** POWER RULE if a power is raised to an exponent, multiply the exponents and dont consider the factors, if this section isnt what you're looking for, maybe the "POWER OF THE PRODUCT RULE" section might explain when it comes to involving factors) FORMULA: (x^m)^n = x^mn (in basic terms, multiply) EXAMPLE: (4^3)^2 = 4^ [3 . 2] = 4^6 *** POWER OF THE PRODUCT RULE The product rule multiplies the factors with the exponents, to visualize what this description meant, please look at the example below: FORMULA: (xy)^m = x^m . y^m EXAMPLE: (3b)^2 = 3^2 . b^2 = 9b^2 (just copy the variables btw) *** POWER OF THE QUOTIENT RULE This rule focuses on distributing the exponent outside the exponent to the two bases, and we meant distributing, copying FORMULA: (x/y)^m = x^m/y^m EXAMPLE: (4/5)^3 = (4^3/5^3) = 64/125 (multiply them with factors) *** ZERO RULE I'll explain this in the simpliest way possible, *ahem*, anything with a zero as the exponent is equal to one, anything, well only numbers 74^0 = 1 34^0 = 1
