Find the indicated real n^th root(s) of a. n = 5 , a = -243

• 3

• -3

• ±3

• no real roots

Match the equivalent expression, ( ³ √ 5 ) ⁴

• 5^4/3

• −5^1/4

• 5^3/4

• 5^−1/4

Solve for x, (x − 5)⁴ = 256

• x = 9

• x = 1

• x = 1 and x = 9

• x = -1 and x = -9

an exponent 1/2 means

• square root

• cube root

• fourth root

• fifth root
