Question

Multiple choice fan and medal Exponents

Answer 1

Multiply the two coefficients together and then multiply the two parts under the sqrt sign and leave them under the sqrt
You get 32sqrt(84)
To simplify the sqrt part, see if you can pull out a perfect square
84 is evenly divisible by 4 and leaves you with 21
In other words, \[32\sqrt{84}=32\sqrt{4(21)}=32\sqrt{2^2(21)}=32(2)\sqrt{21}=64\sqrt{21}\]
