this may not be correct but i really think im right
Answer:
Step-by-step explanation:
Answer:
16. x = 3.0822, -3.0822
17. x = 1.6432, -1.6432
18. x = 1, -1
Step-by-step explanation:
16. log5[(4x²+2)/8] = 1
(4x²+2)/8 = 5¹
4x² + 2 = 40
4x² = 38
x² = 38/4
x² = 19/2
x = +/- sqrt(19/2)
x = 3.0822, -3.0822
17. log7[(2x²-4)(5)] = 1
10x² - 20 = 7¹
10x² = 27
x² = 2.7
x = +/- sqrt(2.7)
x = 1.6432, -1.6432
18. log5[(2x²+8)/2] = 1
x² + 4 = 5¹
x² = 1
x = +/-1
The first thing to do in this case is to perform the division and then compare with the simplified expression to determine the values of a, b, c and d.
We have then:
(12xy ^ 3 + 4x ^ 2y ^ 5) / (4xy ^ 2) =
3x (1-1) and ^ (3-2) + x ^ (2-1) and ^ (5-2) =
3x (0) and ^ (1) + x ^ (1) and ^ (3)
Then, comparing with the simplified expression:
3x ^ ay ^ b + 1x ^ cy ^ d
The value of a is
a = 0
answer
the value of a is 0
