X would be 1392. All you do is the opposite: multiplication! 87*16=1392.1392/87=16. Hope this helps! ^_^
Answer:
maybe 3
2
Step-by-step explanation:
Answer:
x = - 7
Step-by-step explanation:
Using the rule of exponents
× 
= 
Given
× 
= 6², then
= 6²
Since the bases on both sides are equal then equate the exponents
9 + x = 2 ( subtract 9 from both sides )
x = - 7
(2x^2/(1-x^2)) + 3^(1/x) for the first half you can simply divide all terms by the highest power of x to get:
2/(1/x^2-1) as x approaches infinity you have 2/-1=-2
For the second part the exponent approaches zero as x approaches infinity and anything raised to the zero power is equal to 1 so you have:
-2+1=-1
So the limit as x approaches infinity is -1.
Answer:
Step-by-step explanation:
we have
so
substitute the value of 
in the expression
