Question

(Advance Maths) _Solve. Step_by_Step explanation.​

Answer 1

Answer:

x=±15

Step-by-step explanation:

2logx+log(1/3)-log(3/4)=2

logx²+log(1/2)-log(3/4)=2

log[ x²(1/3)(4/3) ] = 2

4x²/9= 10²

4x²=900

x²=(9)(25)

x= ± (3)(5)

x=±15

IDENTITIES USED:---

(1) logA+logB = logAB

(2) logA-logB = logA/B

(3)log T = n

e^(n) = T <or> 10^(n) = T
