CORRECT QUESTION :-

 \bold\looparrowright \bold{10 {}^{y} \times 5 {}^{(2y - 2)}  \times \orange{ 4 {}^{y - 1}}  = 1 }

SOLUTION :-

 \bold\looparrowright \bold{2 {}^{y} \times  {5}^{y} \times 5 {}^{2y - 2}   \times 2 {}^{2y - 2} = 1  }

 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:

\bold\looparrowright \bold{10 {}^{3y - 2} = 1 }

 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:

\bold\looparrowright \bold{10 {}^{3y - 2}  = 10 {}^{0} }

 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:

\bold\looparrowright \bold{3y - 2 = 0}

 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:

\bold\looparrowright \bold{3y = 2}

 \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:
