Answer:
use the rules of exponents
Step-by-step explanation:
The applicable rules of exponents are ...
(a^b)(a^c) = a^(b+c)
(a^b)/(a^c) = a^(b-c)
(a^b)^c = a^(bc)
(ab)^c = (a^c)(b^c)

Applying these to the left-side expression, we can simplify it so it looks like the right side expression.
Step-by-step explanation:
1965 round to the nearest tenth is 1970
Move the decimals two places to the right
Answer:
40 meters long
Step-by-step explanation:
Okie dokie, so because we already have 2 of the three sides, and we know the total perimeter, we just have to subtract the 2 known sides from the perimeter to find the missing side.
The equation should look like this:
120 = 30 + 50 + s
First we need to combine the like terms:
120 = 80 + s
Now, in order to ind the missing side, we need to subtract 80 from both sides:
S = 40
So the missing side is 40 meter long.
Hope this helps :)
