At the title card (0.02), my answer is d) 10000. 10^0 would be 1, and each step of the negative exponent moves the decimal a space to the left, so 10^-3 is 0.001. Then, when we divide isomg that result as the divisor, we take the dividend, 10 and move the decimal three steps to the right, giving us 10000.

real simple if the exponent is negative you "flip" the number. Since we are also dividing by that number it just becomes 10 times 10^3. which of course is 10,000.

Simplest way to solve this problem simply is as given: 10÷10 raise to power minus three= 10÷1/10 over 3= 10×10 to power three= 10*10*10"10=10000 is answer. Logics 10 to power mins 3 is equal to 1/10 to power three by invesing power becomes positive. As per arithmetic rules when ÷ is converted into (× )multiplication, the inverse of 1/10 to power 3 is applied which is 10 to power three

I did it by thinking in terms of fractions (the second method, sort of). 10 to minus 3 = 1/10 cube. 10 divided by 1/10 cube = 10 X 10 cube/1. Which is equal to 10000. Thanks for the review of the rules of exponents. :)

--- < Also, 10 / 1/10 x10 x 10 = 10000 or 10 / .001 = 10000 but is there a way to write 10 to the minus 3 like you write 10 to the 3? -10 x -10 x -10 = -1000 written as 1 /1000. However, squared negative exponents in the denominator are also inverted. If it were 10 to the minus 2 or -10 x -10 = 100, why would it still be inverted into a fraction? It would be very interesting to see how this pans out across a number line. It's amazing to me that a whole number 10 divided by a fraction,.001, is equal to a number greater than itself. .... Ten divided by 5 = 2. Ten divvied by 10 = 1. I am surmising that 10 divided by .001 =- 10,000 pieces less than 1. or 10,000 pieces that are 1 one thousandth the size of the original number. Also how is any number to the zero equal to 1 and not zero?
@katharinegoodell6 ай бұрын
We know that 3/3 or 17/17 or 8/8 = 1 Also 10 to the 3rd power over 10 to the 3rd power = 1. It is less confusing for me to multiply the fraction in this problem by 10 to the 3rd power over 10 to the third power to get rid of negative powers. If I do this the denominator becomes 10 to the o power, which is 1 And the numerator becomes 10 to the first power multiplied by 10 to the 3rd power. I add the exponents for 10 to the 4th power (over 1) which is 10,000. If I haven't done exponents in a long time, I can reteach myself since I know that 10 to the third power means 10 x 10 x 10, and it is to be multipied by 10 (which is the same as 10 to the first power), giving me 4 tens multiplied together, or 10 to the 4th power.

Simple, succinct and powerful! QUESTION: I've been trying to remember an equation from first-year calculus class. All I remember is that the derivative produced the set of all values of x, where, * x < 0, y = 0; * x > 0, y = 0; and * x = 0, y = ±∞ What function will have as its derivative this set of values?

D. Division by a fraction is equivalent to multiplication by its reciprocal. Since 10^-3 is 1/1000 its reciprocal is 1000. 10 * 1000 = 10000.

Came back here to measure my progress and check if I remember the rule. Check! I do. 10 divided by 10 to negative 3 = 10 to the fourth power (a to the m divided by a to the n = a to the m - n) The rest is a piece of cake (1 minus (- 3) = 1 + 3 = 4). So I am left with 10 to the 4th power = 10 000. I "appear" to be an expert in exponents. But don't judge a book by its cover just yet. ;)

Forget the simplicity because you have the knowledge. Think back to what, 5th grade?, this is a hard problem until you understand the rules. And guess what, the rules you don’t really understand until college. They are just rules you are taught to apply,. Until you go get into the fundamentals and understand where the rules are derive from, you just follow the rules. Pedagogy is a whole other topic. I am not a teacher, but my respect goes out to them!

I used it for Solar flare math, inverse square laws, and it even can write code in Python, and C++. If you're interested, you, and or you're students could use it for extra help if needed, as well. It even has a bit of a sense of humor too, if you joke with it, or play with it, it will respond "chuckles", you know, for the kids. May God bless?
