Answer:
–7 is not the arithmetic square root of 49 only in case we are taking it for natural number.
Step-by-step explanation:
- The square root of x is that number which on squaring gives the result as x.
- For example, the square root of 4 is +2 or -2. Because on squaring +2 or -2 we get the number 4.
- Similarly for the case of 49, the square root might be both +7 or -7.
- But if we are taking it as a natural number then -7 is not valid. Like for length, quantity or other sort of things -7 is not the arithmetic square root of 49.

Answer:
949.2
Step-by-step explanation:
To solve this equation, you must use P.E.M.D.A.S...
First, solve 7x9 and 5x2...
7x9= 63 5x2 = 10
So...
1000+50-36+63+8÷10+1
Next, solve 8÷10 and get 0.8
So...
1000+50-36+63+0.8+1
Then, solve 1000 + 50, and 36+63, and that result with 0.8 and that with 1.
So...
1050-100.8
The Solve!
949.2
