 the inverse operation of raising to a power is called taking the ____ root any root of 1 is ___ 1 1 raised to any power equals ___ 1 if we write a little number 4 and then the square root sign then 16 = 2. what is the 16 called, what is the 4 called, what is the 2 called 16 radicand 4 index 2 root what is the square root sign called radical sign if the index number is not written it is understood to be a two if we write a little number 4 and the the square root sign then 16=2.what is the whole expression called radical expression or just a radical what are the 4 orders of operation 1. simplify within the symbols of inclusion. 2. simplify exponents and roots 3. multiply and divide in order from left to right. 4. add and subtract in order from left to right parentheses are called symbols of inclusion when there is no plus or minus sign between parentheses or when there is no plus or minus sign between a number and parentheses what does this indicate multiplication 1. simplify within the symbols of inclusion. 2. multiply and divide in order from left to right. 3. add and subtract in order from left to right order of operation what word is used to describe a space or a solid that has depth as well as lenght and width volume what is an object that has six identical square faces cube we call a geometric figure that occupies a space a geometric solid we call the region on which we stack cubes a base the sides of a solid go straight up from a base to a uniform height, the sides make a right angle where they contract the base,we call these geometric solids what right geometric solids or just right solids volume of right solid = ______ x _____ area of base x height when we multiply a number by a positive power of 10, we move the decimal point to the right, the number of places indicated by the exponent when we write a number this way 0.34 x10 to the 2nd power=34 we call this special way scientific notation when we multiply a number by a negative power of 10, we move the decimal point to the left, the number of places indicated by the exponent the latin work for by is _____ and the word for one hundred is _______. we put these words together in english to form the word _____ by is Per one hundred is CENTUM put together is PERCENT A ______is a comparison of two numbers. We write it as a fraction ratio when we write an equation that consist of two ratios connected by an equals sign like, (3/4=6/8) we say the we have written a --------- proportion we find if helpful to note that the ______ _______ of a true proportion are equal to each other. cross products the cross product can be found by multiplying the upper term (numerator) of one ration by the lower term (denominator) of the other ratio. We call this process ____ _____ cross multiplication when one part of a proportion is a variable, the proportion is a _____ _______ conditional proportions or conditional equations whenever you see the equation DISTANCE=RATExDISTANCE the rate used has time on the bottom(denominator). This rate is called the _____ speed Whenever you see the equation TIME=RATExDISTANCE the rate with time in the numerator, we can ______ to find the ____ required. MULTIPLY TIME Jimmy can drive 60 miles in 1 hour. what are the two ratios that this statement give us 60 miles/1 hour and 1 hour/60miles 60 miles/1hour If you want to know how far you could drive in 2 hours how would you write the equation DISTANCE= 60/1hr X 2hrs
