Answer:
(3/4)^2×(5/7)^2÷(5/7)^3×(4/3)^2
=(3/4)^2×(5/7)^2÷(5/7)^3×(3/4)^-2
=(3/4)^2×(5/7)^2÷(5/7)^3×(3/4)^2 (because the power is even so the power will be positive)
=1/(5/7)^3-2×(3/4)^2-2
=1/(5/7)^1×(3/4)^0
=1÷5/7*1
=1×7/5×1=7/5=1.4 is the answer please check it and mark me as brainliest please hope it helps you dear.
