Question

Plz solve it........​

Answer 1

Answer:

The value of given polynomial is equals to 6.

Explanation is given in the attachment.

Procedure :-)

Firstly we will solve the logarithmic function using some properties of logarithm and find the value of x.

after finding the value of x we can easily calculate the value of given polynomial by putting value of x in the polynomial.

Answer 2

$\huge \bf{solution} \\ \\ \bf{ we \: have }\\ \\ log \: \frac{16}{625} = x(log2 - log5) \\ \\ \implies \: log \: \frac{16}{625} = log \: { \bigg( \frac{2}{5} \bigg)}^{x} \\ \\ \implies \: { \bigg(\frac{2}{5} \bigg)}^{4} = { \bigg( \frac{2}{5} \bigg)}^{x} \\ \\ \bf{compairing \: power \: on \: both \: sides} \\ \\ \implies \: x = 4 \\ \\ A.T.Q. \\ \\ \\ \implies \bf{ {x}^{2} - 3x + 2 }\\ \\ \bf{put \: x = 4 }\\ \\ \implies \: 16 - 12 + 2 = 6$
