Let u be = (-4 , 3), v= (5 , -2) and w= (w1 , w2). Find w1 and w2 so that w = 2u +3v

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
