Question

Giúp mk với mấy bạn ơi❤️

a, \(\sqrt{64}-\sqrt{16}+\sqrt{\left(-5\right)^2}\)  b, \(\sqrt{49}+\sqrt{4}-\sqrt{9}.\sqrt{144}\)

c, \(\sqrt{12}+\sqrt{\left(-5\right)^2}-\sqrt{9}+\sqrt{125}\)

Answer 1

\(a,\sqrt{64}-\sqrt{16}+\sqrt{\left(-5\right)^2}\)

\(=8+4+5\)

\(=17\)

Answer 2

\(b,\sqrt{49}+\sqrt{4}-\sqrt{9}.\sqrt{144}\)

\(=7+2-3.12\)

\(=9-36\)

\(=-27\)

Answer 3

\(a;\sqrt{64}-\sqrt{16}+\sqrt{\left(-5\right)^2}\)

\(=8-4+5\)

\(=9\)

\(b;\sqrt{49}+\sqrt{4}-\sqrt{9}.\sqrt{144}\)

\(=7+2-3.12\)

\(=7+2-36\)

Answer 4

a) \(\sqrt{64}-\sqrt{16}+\sqrt{\left(-5\right)^2}\)

\(=8-4+5\)

\(=9\)

b) \(\sqrt{49}+\sqrt{4}-\sqrt{9}.\sqrt{144}\)

\(=7+2-3.12\)

\(=-27\)

Answer 5

\(a,\sqrt{64}-\sqrt{16}+\sqrt{\left(-5\right)^2}\)

\(=8-4+5\)

\(=9\)

\(b,\sqrt{49}+\sqrt{4}-\sqrt{9}.\sqrt{144}\)

\(=7+2-3.12\)

\(=-27\)
