Square root of 98?

Question

PLease show me step by step PLease im soo lost in Square roots

Answer 1

√ 98 = √(49 x 2) = 7 √2

Answer 2

divide 98 by perfect squares
2 squared is 4, 98divided by 4 is not a whole number
3 squared is 9, 98 divided by 9 is not a whole number
4 squared is 16, 98 divided by 16 is not a whole number
5 squared is 25, 98 divided by 25 is not a whole number
6 squared is 36, 98 divided by 36 is not a whole number
7 squared is 49, 98 divided by 49 is 2
therefore the square root of 98 is the square root of (49x2) and the square root of 49 is 7 and your answer is 7square root 2 and the 2 stays in because it is not nor will it be a perfect square.

Answer 3

I assume you mean simplifying the root?

In that case you just need to find the largest square factor of 98.

That would be 49 because it's a square number (7*7) and 49 *2 = 98 (can't get a bigger square factor)

Now we rewrite the root as the product of two others:

sqrt(98) = sqrt(49) * sqrt(2)

And we simplify:

sqrt(49) * sqrt(2) = (7) * sqrt(2) = 7sqrt2

Answer 4

first you have to find the lcd of 98 which is 2*49 so you have the square root of 2 and the square root of 49..well the square root of 49 is 7 which leaves you with 7 root 2

Answer 5

√98=√(49 x 2)= √(7² x 2)= √7² x √2 = 7 x √2 = 7√2
. . .= 7 x 1.414 = 9.898 . . . Ans
. . ======================

Answer 6

98
=49x2
=7^2x2
square root of 98=7x(2)^1/2

Answer 7

7 sqrt of 2

Answer 8

Sqrt (98)
=sqrt (49*2)
=sqrt (49)*sqrt (2)
=7*sqrt (2)

Or if you didn't want it simplified, just use a calculator.

Answer 9

(1)first factorize 98 into prime factors

(2) then if u have 2 pairs , just choose one only.

and finally multiply those
