Write Squareroot 5x 32 as an absolute Simplify x25 middot x

Write Squareroot (5x - 3)^2 as an absolute Simplify (x^2/5 middot x^-1/x^3/5)^2. Write in exponential form. Assume (5 Squareroot 2x + 7)^2

1) sqrt[(5x -3)]^2

= |5x -3 |

2) ( x^(2/5)x^-1)/x^3/5)^2

use the exponent property : x^a*x^b = x^(a+b) ; x^-a = 1/x^a

(x^(2/5 -1)/x^(3/5))^2

(x^-3/5/x^3/5)^2

[1/x^(3/5+3/5)]^2

[ 1/x^6/5]^2

1/x^12/5

x^-12/5
