Question

Evaluate the expression √27 cubed- the √196

Answer 1

To evaluate the expression √27^3 - √196, we need to calculate the square root of 27 cubed and subtract the square root of 196.

√27^3 = √(27 * 27 * 27) = √19683 ≈ 140.14

√196 = 14

Therefore, the expression becomes:

140.14 - 14 ≈ 126.14

(27^1/2 )^3 - sqrt (196)

27^3/2 - sqrt ( 196)

140.296 - 14= 126.3
