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✌️❤️✌️
