Answer:
a = 3, b = 12, c = 13
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)
___

<em>Additional comment</em>
I find it easy to remember the rules of exponents by remembering that <em>an exponent signifies repeated multiplication</em>. It tells you how many times the base is a factor in the product.
Multiplication increases the number of times the base is a factor.
Similarly, division cancels factors from numerator and denominator, so decreases the number of times the base is a factor.
$57.18 + 256.79 = 313.97
313.97 - 68.42 = 245.55
245.55 - 50.00 = 195.55
195.55 - 31.06 = 164.49
that’s your answer
X= -4y let this be equation 1
x+5y=2 let this be equation 2
substitute equation 1 in 2
-4y + 5y = 2
y=2
substitute the value of y in equation 1
x= -4y
x= -4(2)
x= -8
30,384 feet difference between the two, since the climber is 29,035 feet above sea level you take a positive 29,035 and a -1,349 due to being below sea level, you add the two together with the equation 29,035+1349=30,384 feet
