Answer:
5 over 5
Step-by-step explanation:
You can see that 20x 5 is needed to get the denominator of 100, so you need to multiply the top by 5 too, to get 85/100. Hope this helps.
X should be around 1.5625, assuming that -4 is squared is not in a parenthesis. So, the problem should be -20=-4^2(sqrtx). Divide -20 by -16 to get 1.25. Then square 1.25 and sqrt x to get 1.5625.

<span>let's analyze two cases
</span>
case A) <span>2(√x)−4=10
2</span>√x=10+4----> 2√x=14----> √x=14/2----> square---> x=7²----> x=49
case B)
2√(x-4)=10
√(x-4)=10/2-----> square---> x-4=5²----> x=25+4-----> x=29
