Question

simplify the following​

Answer 1

Answer:

1) 5.618

2) 0.0878

3) 1.5625

4) 1.0485×10^-4

Step-by-step explanation:

1) (-3/4)^2^-3 = (-3/4)^-6 = 5.618

2) (-2/3)^2^-3^-1 = (-2/3)^6 = 0.0878

3) (4/5)^-8^1/4 = (4/5)^-2 = 1.5625

4) (2/5)^3×(2/5)^4×(2/5)^11÷(2/5)^8 = (2/5)^10 = 1.0485×10^-4
