Solve for x in the following equation.
WARRIOR [948]

\huge\text{Hey there!}


\mathsf{5^{x - 2} = 5^8}

\mathsf{5^{x - 2} = 5\times5\times5\times5\times5\times5\times5\times5}

\mathsf{5^{x - 2} = 25\times25\times25\times25}

\mathsf{5^{x - 2} = 625\times625}

\mathsf{5^{x - 2} =390,625}

\large\textsf{Solving for the exponent:}

\mathsf{5^{x - 2} =390,625}

\large\textsf{Take the log (logarithm) to both of the sides:}

\mathsf{log(5^{x - 2} \rightarrow  log(390,625)}

\large\textsf{Simplify it:}

\mathsf{(x - 2) \times(log (5)) \rightarrow log(390,625)}

\large\textsf{Simplify that as well:}

\mathsf{x - 2 = \dfrac{log(390,625)}{log(5)}}

\large\textsf{You get it: }\mathsf{x - 2 = 8}

\large\textsf{ADD by 2 to BOTH of the SIDES:}

\mathsf{x - 2 + 2 = 8 + 2}

\large\textsf{Simplify it:}

\mathsf{x = 8 + 2}

\mathsf{x = 10}


\huge\textsf{Therefore, your answer should be:}

\huge\boxed{\mathsf{x =} \frak{10}}\huge\checkmark

If the roots of a quadratic equation are 1±√5, then the product of the roots is
Drupady [299]
The plus-minus sign represents that there are two possible outcomes.

In this case, we have 1 \pm \sqrt{5}. When we branch out the possibilities we got 2 values: 1 + \sqrt{5} and 1 - \sqrt{5}

Those are the roots of this equation. When they ask their product, they want you to multiply both numbers.

When we multiply them: (1 + \sqrt{5}) \times( 1 - \sqrt{5})

When we FOIL the we get: 1 \times 1 - 1 \times \sqrt{5} + 1 \times \sqrt{5} - \sqrt{5} \times \sqrt{5}

Simplify:
1 - \sqrt{5} + \sqrt{5} - 5
1 - 5 = 6

So the product of the two roots of this equation is 6.
