Step-by-step explanation:
3^2 + 8 ÷ 2 - (4 + 3)
we do what's in parentheses first. (pemdas)
so now we have, 3^2 + 8 ÷ 2 - 7
next exponents, 3^2=9
9 + 8 ÷ 2 - 7
next division, 8÷2=4
9 + 4 - 7
next addition, 9+4=13
13-7
finally subtraction, 13-7=6
final answer: 6
Answer:
425/7
Step-by-step explanation:
I used a calculator. Hope this helped!!
We'll have to repeatedly square both sides of the equation, in order to get rid of the square roots. Squaring a first time yields

Move the 19 to the right hand side:

And square again:

Square one last time:

Let's check the solutions: all these squaring might have created external solutions:

So,
is a feasible solution.
