Answer :
To find the square roots of the given perfect square numbers, we need to determine which number, when multiplied by itself, gives us the original number. Here are the solutions:
(a) [tex]10000[/tex]
The square root of [tex]10000[/tex] is [tex]100[/tex]. This is because [tex]100 \times 100 = 10000[/tex].
(b) [tex]40000[/tex]
The square root of [tex]40000[/tex] is [tex]200[/tex]. This is because [tex]200 \times 200 = 40000[/tex].
(c) [tex]90000[/tex]
The square root of [tex]90000[/tex] is [tex]300[/tex]. This is because [tex]300 \times 300 = 90000[/tex].
(d) [tex]160000[/tex]
The square root of [tex]160000[/tex] is [tex]400[/tex]. This is because [tex]400 \times 400 = 160000[/tex].
(e) [tex]250000[/tex]
The square root of [tex]250000[/tex] is [tex]500[/tex]. This is because [tex]500 \times 500 = 250000[/tex].
(f) [tex]360000[/tex]
The square root of [tex]360000[/tex] is [tex]600[/tex]. This is because [tex]600 \times 600 = 360000[/tex].
(g) [tex]490000[/tex]
The square root of [tex]490000[/tex] is [tex]700[/tex]. This is because [tex]700 \times 700 = 490000[/tex].
(h) [tex]640000[/tex]
The square root of [tex]640000[/tex] is [tex]800[/tex]. This is because [tex]800 \times 800 = 640000[/tex].
To find the square root of a number, you can also use prime factorization or a calculator for larger numbers, although for perfect squares it's often simpler to recognize the squared value.
