The problem is quite hard for me.

(10²)³ / 10² = ?

If anyone can help me thank you.

(10 ^2) ^3 / 10 ^2 (Using ^2 instead of exponent)
= 100 ^ 3 / 10 ^2
= 1,000,000 / 10 ^2
= 1,000,000 / 100
= 10,000

homework's now complete.

(10²)³ / 10² = ?
(10²=20)³ /10² = ?
(20)³=60/10² = ?
60/10² = ?
60/20=3

anyone else tell me I did it WRONG...

Go ahead and anyone else tell me I did it WRONG....

This is wrong... you multiply 10 by 10 when its squared not 10 by 2... the first answer is correct...

Because it is (10*2)=20*3=60/20=3 inside the brackets first and it is multiplication not what you did. How you came across that, I will never know...

Yes we are multiplying but we are multiplying it by itself. For example 10² is 100 because 10*10=100

When you multiply variables of the same kind together, you add the exponents. When dividing variables of the same kind, you subtract the exponent of the second variable from the first.

no no no! First of all you didn't add or subtract them you multioplied them, so even this defense is incorrect... You do not add the exponents in this case, you sove the equation within the parentheses, which would be 10 squared then take that number and cube it... simple math order here... PPMDAS! Parentheses, powers, multiplication, division, addition, subtraction...

You need to learn how to use the comment feature here as well. At least I disagreed with you in a post rather than through rep. I don't personally care about rep, but others here do, esp. the newer ones.

this is how i would do it:



using simple exponent rules.

Ok, you did it WRONG! Lol! :D

Can you explain why you though 10 squared was 20 and not 100?
Was it just a mistake or are you suggesting there is a different way of doing it?

Just wanting to understand! ;)

I was looking at 10squared as being 10*2 and then by 3/10*2=?

On a certain map 3/4 inch represents one mile what distance, in miles, is represented by 1 3/4 inches?

You really should start your own thread for your question instead of tagging onto one over two years old (on a different topic). Imagine the confusion if everyone just tagged onto the same thread all the time.

I suggest you start by drawing two lines next to each other, plotting 3/4" on one, and 1 mile on the other in the same spot. That gives you a visual of what is going on and you may figure it out, or at least get some ideas, from there.
