Question

If a = 7 - 4√3, find the value of a + 1/a​

Answer 1

Explanation:

To calculate a+1/a, we first need to calculate for a.

a = 7 - 4 *
`\sqrt[2]{3}`

square root of 3 = 1.73

a = 7 - 4 * 1.73

a = 7 - 6.9

a = 0.1

0.1 + 1 / 0.1 = 0.1 + 10 = 10.1

Now, in case 4 wasn't being multiplied with the square root of 3, and instead, it was four root of 3, I am gonna do the calculations again:

a = 7 -
`\sqrt[4]{3}`

a = 7 - 1.31

a = 5.69

5.69 + 1 / 5.69 = 5.69 + 0.17 = 5.86

Hope I Helped!
