Simplifying (y5)9(y^5)^9 and (44)7(4^4)^7 Using the Power Property

Apply the Power Property for Exponents to simplify two expressions that each involve a power raised to a power.

(y5)9=y45(y^5)^9 = y^{45}: The base is yy and the two exponents are 55 (inner) and 99 (outer). Multiply the exponents using the Power Property: (y5)9=y59=y45(y^5)^9 = y^{5 \cdot 9} = y^{45}.

(44)7=428(4^4)^7 = 4^{28}: The base is 44 and the two exponents are 44 (inner) and 77 (outer). Multiply the exponents: (44)7=447=428(4^4)^7 = 4^{4 \cdot 7} = 4^{28}.

In both parts the procedure is identical: keep the base unchanged and multiply the inner exponent by the outer exponent, condensing the expression to a single power without expanding into many repeated factors.
