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.
Answer:7
Step-by-step explanation: 10 +10 +x+x=34
20+2x= 34
-20 20
2x=14 x=7
The last bc the + and - are different that means it will be subtracted.
Answer:
∠SQR = 1/2 m ∠SR = 1/2 x 86 = 43°
Answer:
x = 3
Step-by-step explanation:
exterior angle of a triangle is equal to the sum of the measures of the two remote interior angles
97 + x = 64 + 27
x = 97 - 64 - 27 = 6
