If pq =23 and up=1/23 fund the value of u*q*v*p. Explain which properties you used.
Usimov [2.4K]

Given that pq=23 and up=1/23

But question is asking to calculate value of u*q*v*p. which doesn't contains variable "p"

So it seems that you mistyped the equation up=1/23

it should be uv=1/23


Now i will show you how to evalueate u*q*v*p

In given equation pq=23, p and q are together so first we need to rearrange the letters

u*q*v*p

= u*v*q*p {commutative property of multiplication}

= u*v*p*q {commutative property of multiplication}

= (uv)*(pq) {applied parenthesis just for easiness}

Now plug the given values

= (23)*(1/23) {multiplication}

= 23/23 {division}

= 1

Hence final answer is 1.
