98 is 49 times 2 so the square root of 98 is the square root of 49 times the square root of 2. But the square root of 49 is 7 , so the answer is 7 times the square root of 2.
sq. root of 98 =sq. root of 49*2 =7*sq.root of 2 =7*1.414 =9.898
sqrt(245) = sqrt(49*5) = sqrt(49)*sqrt(5) = 7*sqrt(5)
sq rt(49) xa4= 7a4
you cant simplify a square root
This is clearer if you use fractional powers, at least for the intermediate steps. The fourth root of 32x2y2 is (32x2y2)1/4, or 31/2x1/2y1/2. In other words, the square root of 3xy.
A square root of a negative number is not possible because there aren't two numbers that are the same that can be a negative number. Though, you can simplify it in terms of i (imaginary number), you just change it into √49 X √-1 The square root of 49 is 7 The square root of -1 is i, So it becomes 7 X i Thus making the answer 7i
Square root of 40 can be written as 49 to the power of half. So, the 2 in the half gets cancelled with the 4 leaving 49 square. And 49 square is 2401.
