Hello...❤️..

ɪ ᴛʜɪɴᴋ ᴛʜᴇ ϙᴜᴇsᴛɪᴏɴ ɪs x=(√7+43–√) ɴᴏᴛ 7–√+43–√ ( ɪғ sᴏ , ᴛʜᴇɴ ᴀʟʀᴇᴀᴅʏ ᴀɴsᴡᴇʀ ɪs ɢɪᴠᴇɴ)

sᴏ,

x=(√7+43–√)

ɴᴏᴡ

7+4(√3)=22+2∗2∗3–√+(3–√)2

=(2+3–√)2

ʜᴇɴᴄᴇ 7+43–√−−−−−−−√ = 2 +3–√

sᴏ x=2+(√3)

1/x=1(2+3–√)

=2−3–√22−3–√2 [ ᴍᴜʟᴛɪᴘʟʏɪɴɢ ɴᴜᴍᴇʀᴀᴛᴏʀ ᴀɴᴅ ᴅᴇɴᴏᴍɪɴᴀᴛᴏʀ ʙʏ 2+(√3) ]

=2−3–√4–3

=2+3–√

sᴏ 1/x=2−3–√

sᴏ x+1x=(2+3–√)+(2−3–√)=4

Thank you✌️❤️✌️
