  • Question 12 of 16

    The equation for calculating total resistance in a parallel circuit (for any number of parallel resistances) is sometimes written like this:


    Rtotal = (R1−1 + R2−1 + …Rn−1)−1



    Re-write this equation in such a way that it no longer contains any exponents.

    Question 3, answer - the ‘+’ symbol is missing from ‘= a^(m+n)’.
    Question 7, question and answer - second equation should have a multiplication symbol, not the ‘variable x’.
    Question 8, question and answer - second equation should have a multiplication symbol, not the ‘variable x’.
    Question 9, question - the ‘+’ symbol is missing between ‘4.5154 ‘+’ 14’.
    Question 9, answer:
    - the ‘+’ symbol is missing: 10 − 25 ×2 ‘+’ 5 = −35
    - the ‘+’ symbol is missing: −8 ‘+’ 10^3 ×51 = 50992
    - the ‘+’ symbol is missing: 12^4 ×(3 ‘+’ 11) = 290304
    Question 9, question and answer: The square root should enclose the whole equation, and the equation should have a multiplication symbol, not the ‘variable x’.
    Question 13, question and answer: The table columns need spacing and the ‘+’ symbol is missing from the headings ‘2x + 1’.

    These are all correct in the PDF version.
