Question

If logx/10 = a then 10^a–1 in terms of x is
​

Answer 1

Answer:

According to the rules of logarithm we know that log 1000= 3. As we by deafult have 10 in the base accordingly to the main rule. We get 10³= 1000. Therefore,

log x= -1

x^ -1 =10

1/x=10

X= 1/10

But accordin to calculus we have ‘e' by deafult in the base. Therefore,

log x=-1

X^-1 = e

1/ x= e

X= 1/e

Answer 2

Answer:

logx/10 = a

logx = 10*a

x = 10^(10*a)

x = (10^a)^10

Taking 10th root on both sides

x^(1/10) = 10^a

x^(1/10) - 1 = 10^a - 1
