How do you solve √x(√9−4÷3)=√25?
1 Answer
Remember PEMDAS
Explanation:
- Do inside (), and turn division to fraction. It will look like
√x⋅(3−43)=√25
- To finish (), you need LCD. LCD will be
3 , and turn 3 to(93) .
What is
√x⋅(53)=√25
- Take square root of
25 . It will look like
√x⋅(53)=5
- Multiply each side by
35 . It will look like
√x⋅53⋅35=5⋅35
√x=3
- Now take the square of each side. It will look like
(√x)2=32
x=9
