9x^{7/2}-63=0

9 x^{\frac{7}{2}} - 63 = 0

x = 7^{\frac{2}{7}}

Decimal Notation

x = 1.74363 \dots

Solution steps

9 x^{\frac{7}{2}} - 63 = 0

Move

63

to the right side

9 x^{\frac{7}{2}} = 63

Divide both sides by

9

x^{\frac{7}{2}} = 7

Take both sides of the equation to the power of

\frac{2}{7} : x = 7^{\frac{2}{7}}

x = 7^{\frac{2}{7}}

Verify Solutions:

x = 7^{\frac{2}{7}}

True

The solution is

x = 7^{\frac{2}{7}}

\frac{6 ( x + 4 ) - 4}{2} = 4

x, x^{0.7} = 2

3 = 16 m - 5

25 - x^{2} - 4 25 - x^{2} = 0

x^{\frac{1}{6}} = 2
