Multiplying and Dividing Exponents are very easy.
When they are multiplied, we add the exponent numbers together.
When they are divided, we subtract the exponent numbers.
In this example, h^{-18}* h^3/h^{0}
We can conclude that h^{0} is 1 because,
any number to the power of 0 is 1
\frac{ h^{-18}*  h^{3} }{1}=h^{-18} *  h^{3}
take the exponents alone:
-18+3 (Because it is multiplication) =-15
Final answer: h^{-15}

draw a rectangle around it:

the widest part is from about -3 to 2 which is 5 units wide

height is from 3 to -4, which is 7 units

5*7 = 35

the top and bottom are angled so you can subtract a little for that

 so I would estimate around 32 square units

A Fraction Number: The sum of the numerator and denominator is 40. if its value is 3/5 after simplifying, what is the fraction b
katrin2010 [14]
Here: Fraction = 3/5
Let, original fraction (before simplifying) = 3x/5x
Then, 3x + 5x = 40
8x = 40
x = 40/8
x = 5

So, 3x = 3(5) = 15 & 5(5) = 25

In short, Your Answer would be 15/25

Hope this helps!
