`10^(3x)=125` then `10-2x=`?

If 5^(3x)=\ 125\ and 10^y=0. 001 find x\ a n d\ y

((log)_(10)(x-3))/((log)_(10)(x^2-21))=1/2 then find x.

If 10^(x-1) + 10^(-x-1) = (1)/(3) , then x equals to

Consider the quantities such that x_(1),x_(2),….x_(10),-1 lex_(1),x_(2)….,x_(10)le 1 and x_(1)^(3)+x_(2)^(3)+…+x_(10)^(3)=0 , then the maximum value of x_(1)+x_(2)+….+x_(10) is

If y=3 x + 6 x^(2) + 10 x^(3) +… then x =

7/10-x=3/10

If log_(10)2,log_(10)(2^(x)-1) and log_(10)(2^(x)+3) are in A.P then the value of x is

Solve the equation 10^((x+1)(3x+4))-2*10^((x+1)(x+2))=10^(1-x-x^(2)).

If x+ 5y= 10 , find the value of x^(3) + 125y^(3) + 150xy - 1000

If 5^(3x^(2)"log"_(10)2) = 2^((x + (1)/(2))"log"_(10) 25) , then x equals to
