Question

Me ayudan con esto plis no le entiendo (por favor!!! Me ayudan?)

Answer 1

Respuesta:

a) 3

b) v2 = 1,4142...

c) v7 = 2,6457...

d) 3/2

e) 0.605

Explicación paso a paso:

a) 9cm²

${x}^{2} = 9 \\ \sqrt{ {x}^{2} } = \sqrt{9} \\ x = 3$

b) 2cm²

${x}^{2} = 2 \\ \sqrt{ {x}^{2} } = \sqrt{2} \\ x = \sqrt{2} \\ x = 1.4142...$

c) 7cm²

${x}^{2} = 7 \\ \sqrt{x} = \sqrt{7} \\ x = \sqrt{7} \\ x = 2.6457...$

d) 9/4 cm²

${x}^{2} = \frac{9}{4} \\ \sqrt{ {x}^{2} } = \sqrt{ \frac{9}{4} } \\ x = \sqrt{ \frac{9}{4} } \\ x = \frac{3}{2}$

e) 1,21 cm²

${x}^{2} = 1.21 \\ \sqrt{ {x}^{2} } = \sqrt{1.21} \\ x = \sqrt{1.21} \\ x = 0.605$
