Take a^x = bc raise both sides to the power yz (a^x)^(yz) = (bc)^(yz) a^(xyz) = (bc) ^(yz) a^(xyz) = (b^y)^z (c^z)^y Put b^y = ca c^z = ab a^(xyz) = (ca) ^z (ab) ^y = c^za^(yz)b^y substitute b^y = ca c^z = ab a^(xyz) = ab a^(yz)ca = a^2a^4 Definition A literal is any Boolean variable x or its complement x' Truth Tables of Boolean functions Much like the truth tables for logical propositions If f(x,y,z, ) is an nvariable Boolean function, a truth table for f is a table of n1 columns (oneTo ask Unlimited Maths doubts download Doubtnut from https//googl/9WZjCW If `a^x=b, b^y=c and c^z=a` then find the value of xyz Text Book Of Anatomy And Physiology For Nurses E 0 0 1 Di 0 Lt J Lt Lt Z H Oi Q H 0 X Lt H 312 3 3 Circle Around Z¶ "¯^ "Y c[ubN
