Communicate Mathematical Ideas Why do you subtract exponents

Mathematics
1 answer:
zysi [14]3 years ago
5 0

Answer:

We subtract exponents when diving powers with the same base because they eventually get canceled out when written in expanded form.

Step-by-step explanation:

For example, if we expand the given fractions:

10^3/10^1 = 1000/10 = 100 = 10^2

Now, if we subtract the exponents we get the same result.

10^3-1 = 10^2

So, a^m/a^n = a^m-

n is one of the exponent rules which saves time and makes calculation easier.

Step-by-step explanation:

We are given that there are 132 boys and 14 adults. Since the question is only asking for the ratio of adults to boys, we don't have to worry about the number of girls in this question. From here, we see that the question is asking for the ratio of adults to boys, so we put it in that exact order. Our answer is 14 to 132.

mihalych1998 [28]
A/b+c/b=(a+c)/b
make bottom number same

multiply by 1 or x/x where x=x
easy way is
if you had
a/b+c/d
multiply a/b by d/d and multiply c/d by b/b

2/5 times 4/4=8/20
2/4 times 5/5=10/20

add

8/20+10/20=(8+10)/20)=18/20=9/10

I should have simplified 2/4 to 1/2 first
