(3xy)^2x^4y simplifying an expression

Step-by-step explanation:

The problem needs application of law of indices

This means common power for terms can be applied to each term individually.

Separate power for the terms having  same base can be added together.

_______________________________________________________

we will be using these law of indices in the problem

applied the first rule of indices as mentioned above

applied the second rule of indices as mentioned above

Thus, simplified form of (3xy)^2x^4y  is .

20

step-by-step explanation:

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
