Answer:

First: 15

Second: 21

Third: 45

Step-by-step explanation:

In order to create the equation we need to represent the evenings with an alebraic term, in thsi case we are going to represent the second evening with an X

Second evening:x

The first night she got 6 fewer calls than the second: Second-6=x-6

The third night she received 3 times the first: 3(first night)=3(x-6)

The equation is First Night plus second night plus third night equals 81.

First+second+third=81\\x+(x-7)+3(x-6)=81\\x+x-7+3x-18=81\\5x=81+21+6\\5x=105\\x=\frac{105}{5} \\x=21

So the first evening he received 15 calls, the second he received 21 and the third one he received 45.

What is the final product? ^5sqrt4x^2 ^5sqrt4x^2
AnnyKZ [126]
For this case we have the following expression:
 ^ 5sqrt4x ^ 2 ^ 5sqrt4x ^ 2
 Rewriting the expression we have:
 ((4x ^ 2) ^ (1/5)) ((4x ^ 2) ^ (1/5))
 For power properties we have:
 (4x ^ 2) ^ (1/5 + 1/5)
 (4x ^ 2) ^ (2/5)
 Rewriting we have:
 (16x ^ 4) ^ (1/5)
 ^ 5sqrt16x ^ 4
 Answer:
 
^5sqrt16x^4
