Solve problems with or without a calculator Level 4

Understand index notation with fractional powers, for example knowing that n1/2 = √n and n1/3 = 3√n for any positive number n. Convert numbers between ordinary and standard form. For example: 734.6 = 7.346 x 102. 0.0063 = 6.3 x 10-3. Use standard form expressed in conventional notation and on a calculator display. ................
