Given: 2 root 7 × root 8 ×5 root 3 whole divided by 3 root 3 × root 15 ×root 42
To find: Simplify the above.
Solution:
Now we have given:
{ 2√7 x √8 x 5√3 } / { 3√3 x √15 x √42 }
Now we can write it as:
{ 2√7 x √2 x √2 x √2 x √5 x √5 x√3 } / { 3√3 x √3 x √5 x √7 x √3 x √2 }
Cancelling the similar terms from numerator and denominator such as √2, √3, √5 and √7, we get:
{ 2 x √2 x √2 x √5 }/ { 3√3 x √3 }
{2 x √5 } / 9
So the final simplification is:
2√5/9 = 0.4969
