SL 1.5—Integer exponents and logarithms Topic Practice
SL 1.5—Integer exponents and logarithms Topic Practice
Practise rewriting powers, logarithms and number bases, including exact log values, prime factors, radicals and base arithmetic.
How this is tested
- rewrite logs such as log10(1/a) using index laws and log laws to obtain exact values
- convert between bases or use digit divisibility conditions to determine unknown digits in a base number
- simplify powers and radicals, including expressions such as (1-sqrt(3))^2 and integer remainders
