Identify base and exponent: Identify the base and the exponent in (−6x2y4)4.In (−6x2y4)4, the base is −6x2y4 and the exponent is 4.
Apply power of power rule: Apply the power of a power rule, which states that (am)n=am∗n.(−6x2y4)4=(−6)4∗(x2)4∗(y4)4
Calculate each part: Calculate each part separately.First, calculate (−6)4:(−6)4=64, because the negative sign becomes positive when raised to an even power.64=6×6×6×6=1296Next, calculate (x2)4:(x2)4=x2×4=x8Finally, calculate (y4)4:(y4)4=y4×4=y16
Combine results: Combine the results from Step 3.(−6x2y4)4=1296×x8×y16
