State whether each equation is true or false.\ (a)

(p+q)^(2)=p^(2)+q^(2)

\ (b)

\\\\sqrt(ab)=\\\\sqrt(a)\\\\sqrt(b)

\ (c)

\\\\sqrt(a^(2)+b^(2))=a+b

\ (a)

(1+TC)/(C)=

1 + T\ (c)

(1)/(x-y)=(1)/(x)-(1)/(y)

\ (1)

((1)/(x))/((a)/(x)-(b)/(x))=(1)/(a-b)

9. State whether eacl equation is true or false. (a) (p+q)2=p2+q2 (b) ab=6b (c) a2+b2=a+b (a) C1+TC=1+2 (6) xy1=x1y1 (1) 1/xb/x1/x4b1
