Question

a²= b²+ c²
x = 8² + 6²

Answer 1

$\large\boxed{\begin{array}{l} \sf{a {}^{2} = b {}^{2} + c {}^{2} } \\ \sf{x {}^{2} = 8 {}^{2} + 6 {}^{2} } \\ \sf{x {}^{2} = 64 + 36 } \\ \sf{x {}^{2} \: = \: 100} \\ \sf{x = \sqrt{100} } \\ \sf{x = 10}\end{array}}$

Answer 2

Vamos là.

a²= b²+ c²

x² = 8² + 6²

x² = 64 + 36 = 100

x = 10
