Question

scale of rectifier instrument​

Answer 1

Answer:

a^2-b^2

Step-by-step explanation:

LCM*HCF=1ST NUM*2Nd NUM

(a+b)*(a-b)P=P*X ,,, x=a^2-b^2

Answer 2

Answer

c,a^2 -b^2

Step-by-step explanation:

let x be another no.

LCM =(a+b)

HCF=P(a-b)

first no.=P

Acc to the sum

first no.*second no.=LCM*HCF

P*x=(a+b)*P(a-b)

x=(a+b)(a-b). // divided by P

x=a^2-b^2.
