Question

If a= √5 + 3, find 1/a^2 + a^2

Answer 1

Answer:

Step-by-step explanation:

a=\sqrt {5} + 3

a=2.23606798+3

a=5.23606798

• \frac{1}{a^{2} } = \frac{1}{ 5^{2} }

                            =\frac{1}{ 25 }

                            =0.04

•             a^{2} =5^{2}

                            =25
