Question

if a +1/a=10 find the value of a^2+1/a^2​

Answer 1

Answer:

98

Step-by-step explanation:

a + $\frac{1}{a}$ = 10

squaring both sides :

$(a + \frac{1}{a} )^{2} = 10^{2} \\\\a^{2} + \frac{1\\}{a^{2} } + 2 = 100\\\\a^{2} + \frac{1\\}{a^{2} } = 100 -2 \\\\a^{2} + \frac{1\\}{a^{2} } = 98$
