Answer 1

Given :-

x² × 3² = 90

To Find :-

Value of x

Solution :-

x² × (3)² = 90

x² × (3 × 3) = 90

x² × 9 = 90

9x² = 90

x² = 90/9

x² = 10

x = √10

x = ±√10

Hence

Value of x is ±√10

Answer 2

Answer:

${x}^{2} \times {3}^{2} = 90 \\ {x}^{2} = 10 \\ x = | \sqrt 10 |$

Step-by-step explanation:

${x}^{2} \times {3}^{2} = 90 \\ ({3x})^{2} = 90 \\ 3x = | \sqrt{90} |\\ x = | \frac{ \sqrt{90} }{3} | \\ x = | \sqrt{10} |$
