What is law 1 of the rules of indices?

Which law are we using when we subtract the powers?

Can you write a large number in standard form?

Do you remember how to add together two numbers written in standard form?

You need to remember the previous three laws

Coefficients (numbers in front) are affected by the operation in the question, not the law

Law 4: Anything to the power of 0 is equal to 1

Law 5: with negative powers, we can rewrite to 1 over the remaining parts

Law 6: in fractional powers, the denominator is the root and the numerator is the power underneath the root

Positive powers => large numbers

Negative powers => small numbers
