Ans is 16/9 . But I want the method

Step-by-step explanation:

● 5 [ (27/8)^2 ÷ (81/4)^3 ] × 6^4

● 5 [ 27^2/8^2 ÷ 81^3/4^3 ] × 6^4

● 5 [ 27^2/8^2 × 4^3/81^3] × 6^4

● 5 [ 27^2 × 4^3 / 8^2 × 81^3] × 6^4

● 5 [ (3^3)^2 × 4^3 / (4×2)^2 × (9^2)^3]×6^4

● 5 [ 3^6 × 4^3 / 4^2 × 2^2 × 9^2 ×2^3]×6^4

● 5 [ 3^6 × 2^6/2^9 × 3^4 ] × 6^4

● 5 [ 3^2 /2^3] × 6^4

● 5 [3^2 × 6^4 / 2^3]

● 5 [ 3^2 × 2^4×3^4 / 2^3]

● 5 [ 3^7 × 2]

step-by-step explanation:

quartic functions has x = –1 and x = –2 as its only two real zeroes:

f(x) = a(x+2)(x+1)   a: real number

x=half
