Changing from Radical to Rational Exponent notation and reverse Radical Notation vs. Rational Notation
Finding the nth root of a: • If n = m, and a = x, this is equivalent to: • So: If n = 2, and a = 81, • If n = 3, and a = -8, • If n = 64, and a = 0, • If n = 49, and a = -2,
Directions: Solve • x3 = -216 • x4 + 22 = 2423 • 6x5 + 32 = 196640
Solve: • (x – 13)4 = 16 • -x2 = -144
Application Phillip Darlington discovered a rule of thumb that relates an island’s land area to the number s, of reptile and amphibian species the island can support by the model A =0.0779s3. If the area of Puerto Rico is roughly 4000 square miles, about how many reptile and plant species can it support?
Last Slide – On Your Own • Solve: 3x5 – 11 = 718 • Solve: (x – 2)2 = 100 • Evaluate: 2161/3 = • Evaluate:
