<h3><u>Write 6^8 • 6^7 as a single power:</u></h3>

<em><u>Solution:</u></em>
Given that,
We have to write 6^8 • 6^7 as a single power
Given is:

<em><u>Use the following law of exponent</u></em>

When, the base is same, powers gets added
Therefore,

Thus the given is written as a single power
115*20=2300.

Second mechanic 5 hours
Answer:
1/6
Step-by-step explanation:
Because because there are six books in total and she only red 5 in the way
If you simplify the expression you will get 18x - 15.
X+y=11
x is longer than y
x>y
x is 4 less than 4 times y
x=-4+4y
sub back
x+y=11
-4+4y+y=11
-4+5y=11
add 4 to both sides
5y=15
divide both sides by 5
y=3
sub back
x=-4+4y
x=-4+4(3)
x=-4+12
x=8
the pieces are 8ft and 3ft
