Question | Answer |
---|---|
Solve 4^1/2 (Simplify if possible) | 4^1/2= √4= 2 |
Solve 625^1/4 (Simplify if possible) | 625^1/4= √625= 5 |
Use radical notation to solve. 5x^1/2 | 5x^1/2= 5*(x^1/2)= 5√x |
Use radical notation to solve. (36x^4)^1/2 | (36x^4)^1/2= √36x^4= 6x^2 |
Use radical notation to solve. (1/27)^1/3 | (deg denotes degree of root) (1/27)^1/3= (deg3)√1/27= 1/3 |
Use radical notation to solve. (-3125)^1/5 | (deg denotes degree of root) (-3125)^1/5= (deg5)√-3125= 5 |
Make positive exponent. 1/x^-3/5 | 1/x^-3/5= x^3/5 |
Use law of exponents to solve. x^2/7 * x^6/7 | x^2/7 * x^6/7= x(2/7 +6/7)= x^8/7 |
Factor 7/2 from expression x^7/2 + x^3/2 | x^7/2 + x^3/2= x7/2(1+x^3/2) |
Use rational exponents to write as a radical expression. (deg4)√x^3 * (deg2)√x * (deg7)√x | (deg4)√x^3 * (deg2)√x * (deg7)√x = x^3/4 + ^1/2 + ^1/7= x^25/28 = (deg28)√x^25 |
