9^{2} + x^{2} = 1 0^{2}

x = 9919, x = - 9919

Decimal Notation

x = 99.59417 \dots, x = - 99.59417 \dots

Solution steps

9^{2} + x^{2} = 1 0^{2}

Square both sides:

81 + x^{2} = 10000

81 + x^{2} = 10000

Solve

81 + x^{2} = 10000 : x = 9919, x = - 9919

x = 9919, x = - 9919

Verify Solutions:

x = 9919

True

, x = - 9919

True

The solutions are

x = 9919, x = - 9919

y = 3 + y^{2} - 3

\frac{1}{1 - x ^{2}} = 1.55

4 (1 + x)^{2} = 6

x^{\frac{1}{3}} = 3

x, x + 4 x y + 2 y = a
