Question

find value of a : 32^2=2a^2​

Answer 1

Answer:

Step-by-step explanation:

32²=2a²

=> 32²=2a²

=>32×32=2a²

=>a²=32×16

=>a²=512

=>a=√512

=>a=16√2

Answer 2

Answer:

${32}^{2} = 2 {a}^{2} \\ \therefore 1024 = 2 {a}^{2} \\ \therefore \frac{1024}{2} = {a}^{2} \\ \therefore512 = {a}^{2} \\ \therefore \: a = \sqrt{512} \\ \therefore \: a = \sqrt{256 \times 2} \\ \therefore \: a = 16\sqrt{2}$
