Answer 1

hello friend

x/√128=√162/x

x²=√162×128

x²=√20736

x²=144

x=±12....your answer

Answer 2

Given,

• x\√128=√162\x is given.

To find,

• We have to find the value of x.

Solution,

We can simply find the value of x by simplifying the roots of the given numbers.

            x\√128=√162\x

By Cross-multiplying, we get

                  x² = $\sqrt{162} * \sqrt{128}$

                  x²  = $\sqrt{2*3*3*3*3} * \sqrt{2* 2*2*2*2*2*2}$

                  x²  = $\sqrt{2*3*3*3*3*2* 2*2*2*2*2*2}$

                  x²  =  $\sqrt{20736}$

                  x²  = 144

                  x   = $\sqrt{144}$

                  x   = ±12

Hence, if x\√128=√162\x, then the value of x is ±12.
