Question

doprowad wyrażenia do najprostszej postaci.

a) (x^3:x:x):(x^5:x^4)

b) a^17 : [(a^4:a)*a^3]

c)x^6*y^7*x^2*y*x^0

d) a^5*b*a^0*b^4*a^2

^ = potęga

Answer 1

A) (x^3:x:x):(x^5:x^4) = (x^2:x):x = x:x = 1
b) a^17 : [(a^4:a)*a^3] = a^17 : (a^3 * a^3) = a^17: a^6 = a^11
c) x^6 * y^7 * x^2 * y * x^0 = x^8 * y^8 * 1 = x^8 * y^8
d) a^5 * b * a^0 * b^4 * a^2 = a^7 * b^5 * 1 = a^7 * b^5
