The first step for solving this expression is to divide both sides of the equation by 5². -(6 - 2)z = -10 × [tex]( \frac{10}{5}) [/tex]² Subtract the numbers in the first parenthesis. -4z = -10 × [tex]( \frac{10}{5}) [/tex]² Now,, to raise a fraction to a power,, you must raise the numerator and denominator to that power. This will look like the following: -4z = -10 × [tex] \frac{ 10^{2} }{ 5^{2} } [/tex] Reduce the fraction with 5². -4z = -10 × 2² Evaluate the power. -4z = -10 × 4 Multiply the numbers on the right side of the equation. -4z = -40 Lastly,, divide both sides of the equation by -4 to get your final answer. z = 10 Let me know if you have any further questions. :)
