Question

Explain why 7 + √9 is not equal to √7+9 .

Answer 1

Answer:

The storage units are one of the most important parts of a CPU which stores a large amount of data. The largest storage devices inside of a CPU is hard drives. ... The hard drives are also known as ROM of the CPU.

Answer 2

Answer:

$\red\dashrightarrow\underline{\underline{\sf \green{We \: Know \: that \sqrt{9} = 3}} }$

$\red\dashrightarrow\underline{\underline{\sf \green{R.H.S.}} }$

$\red\dashrightarrow\underline{\underline{\sf \green{7 + \sqrt{9} }} }$

$\red\dashrightarrow\underline{\underline{\sf \green{7 + 3 = 10 }} }$

$\red\dashrightarrow\underline{\underline{\sf \green{L.H.S. }} }$

$\red\dashrightarrow\underline{\underline{\sf \green{ \sqrt{7} + 9 }} }$

$\red\dashrightarrow\underline{\underline{\sf \green{2.64 + 9 = 11.64(approx.) }} }$

$\red\dashrightarrow\underline{\underline{\sf \green{ L.H.S.≠R.H.S.}} }$

Hence Proved that 7+√9 is not equal to √7+9
