For this case we have the following expression:
<span>

By properties of exponents we have:
Same basis, the exponents are added.
We have then:

Then, rewriting the exponent we have:

Therefore, an exponent to rewrite the expression is:
2
Answer:

Answer:
I= 84
Step-by-step explanation:
for

since D is the rectangle such that 0<x<3 , 0<y<3

Number 1 = 17
number 2 = 72
number 3 = 24
work:
the three numbers are symbolized as x, y, and z
x + y + z = 113
number 2 (y) is 3 times the third number (z) so
y = 3z
so x + 3z + z = 113
the first number (x) is 7 less than than the third number (z) so
x = z - 7
so z -7 + 3z + z = 113
5z - 7 = 113
5z = 120
z = 24
x = 17
y = 72

8 foot path
1st step = 8/2 = 4ft
2nd step = 4/2 = 2ft
3rd step = 2/2 = 1ft
4th step = 1/2 = 1/2ft
So he covered 7 1/2 ft (or 7.5ft)
