Answer:
5x^2+2x-432
Step-by-step explanation:
15x^2+x-215×2+x−2
=15x^2+x-430+x−2
=15x^2+x+x-430-2
=15x^2+2x-432
Answer:
1. 6
2. 23
Step-by-step explanation:
1.
logx+1 ( x^2 + 2x + 1)^3
= 3logx+1 ( x^2 + 2x + 1)
= 3 logx+1 (x + 1)^2
= 6 logx+1 (x + 1) Now the logx+1 x+1 = 1 so
The answer is 6.
2.
log11 11^23
= 23 log11 11
As in question 1 log11 11 = 1
So the answer is 23.
