The sixth power of (A's Square b) / the fifth power of (A's Square b)

The sixth power of (A's Square b) / the fifth power of (A's Square b)


(a²b)^6/(a²b)^5
=a^(12-10)*b^(6-5)
=a²b



The square of (a to the third power, B to the ninth power) multiplied by (a to the sixth power, B to the third power)=


The square of (a to the third power, B to the ninth power) multiplied by (a to the sixth power, B to the third power)
=a^6b^18*a^6b^18
=a^12b^36
=The 12th power of a and the 36th power of B



Let f (x) = x2 + BX + C satisfy f (1) = - 4, f (2) = - 3 / 5 · f (4), and find the minimum value of this function


∵ f (x) = x & # 178; + BX + CF (1) = 1 + B + C = - 4 ∵ B + C = - 5 C = - 5-b (1) ∵ f (2) = - 3 / 5F (4) ∵ 4 + 2B + C = - 3 / 5 (16 + 4B + C) 20 + 10B + 5C = - 48-12b-3c22b + 8C = - 6811b + 4C = - 34 (2) substitute (1) into (2) to get. 11b-20-4b = - 347b = - 14 ∵ B = - 2C = - 3 ∵ f (x) = x & # 178; - 2
