Identify base and exponents: Identify the base and the exponents in (−4x2y5)4.In (−4x2y5)4, the base is −4x2y5 and the exponent is 4.
Apply power rule: Apply the power rule (a∗b)n=an∗bn to the expression.(−4x2y5)4 can be written as (−4)4∗(x2)4∗(y5)4.
Calculate each part: Calculate each part separately.First, (−4)4=256 because a negative number raised to an even power is positive.Second, (x2)4=x(2∗4)=x8 because of the power of a power rule, which states that (am)n=a(m∗n).Third, (y5)4=y(5∗4)=y20 for the same reason.
Combine results: Combine the results from the previous step. The expression simplifies to 256×x8×y20.
Write final expression: Write the final simplified expression.The fully simplified form of (−4x2y5)4 is 256x8y20.
