Question

Find x if:
1)2log4 + log5-log10=logx
2)log30-log5^2=logx
3)log8+logx^2=logx
4)log(x+2)-log^4=log3x
5)log (x-1)+log^3=logx
guys I want the answer step by step,
please answer me fast​

Answer 1

above is your answer mate

Answer 2

Answer: solve these by using the below identities,

1)loga+logb=log ab

2)log(a/b)=loga-logb

A)2log 4+log 5-log 10=logx

log 16+log 5-log10=logx

log(80)-log(10)=log x

logx=log(80/10)

X=8

B)log 30-log 25=logx

logx=log(6/5)

X=6/5

C)log 8+logx²=logx

log8+2logx=logx

logx=-log 8

X=-8

Solve the other two By the same method......
