Question

√3+7√27=21√3 is true​

Answer 1

Question:—

State whether the equation √3+7√27=21√3 is true

____________________

Answer:—

Solving LHS we get:-

==>√3+7√27

Factorising it to the simplest form we get:-

==>√3+$(7 \times √3 \times √3 \times √3$ )

==>√3+$(7 \times 3 \times √3$ )

==>√3+21√3

Taking √3 common we get:-

==>√3(21 $\times$ 1)

==>21√3

★ Hence the equation √3+7√27=21√3 is correct.

Answer 2

Answer: UR REQUIRED ANSWER ;-

QUESTION :-

√3 + 7 √27 = 21 √3  is true statement ?

SOLUTION :

by solving LHS term :

√ 3 + 7√27

by facatorising this into simplest form we get :

⇒ √ 3 + [ 7 ×( √ 3 × 3 × 3  ) ]

⇒ √ 3 + [ 7 × 3 ( √3 )]

⇒ √ 3 + 21 √ 3

Taking √ 3 common , then we get :-

⇒ √ 3 ( 21 × 1 )

⇒ 21 √3 .

so , LHS = RHS .

therefore , the statement is true .
