\(2\sqrt{3}-\sqrt{13-4\sqrt{3}}=2\sqrt{3}-\sqrt{13-2.2\sqrt{3}}\)

\(=2\sqrt{3}-\sqrt{\left(2\sqrt{3}\right)^2-2.2\sqrt{3}+1}\)

\(=2\sqrt{3}-\sqrt{\left(2\sqrt{3}-1\right)^2}=2\sqrt{3}-2\sqrt{3}+1=1\)

Ta có: `hat(xAz)+hat(zAy)=180^@`

Mà `hat(xAz)=5.hat(zAy)` (GT)

`=>5.hat(zAy)+hat(zAy)=180^@`

`=>6.hat(zAy)=180^@`

`=>hat(zAy)=180^@ : 6=30^@`

``

+) `hat(xAz)=5.hat(zAy)=5.30^@=150^@`

+) `hat(xAt)` và `hat(zAy)` đối đỉnh `=> hat(xAt)=hat(zAy)=30^@`

24 - 16(x - 1/2) = 23

=> 16(x - 1/2) = 24 - 23

=> 16(x - 1/2) = 1

=> x - 1/2 = 1/16

=> x = 1/16 + 1/2

=> x = 9/16

\(24-16(x-\frac{1}{2})=23\)

\(16(x-\frac{1}{2})=24-23\)

\(16(x-\frac{1}{2})=1\)

\(x-\frac{1}{2}=\frac{1}{16}\)

\(x=\frac{1}{16}+\frac{1}{2}\)

\(x=\frac{9}{16}\)

Vậy số thực x cần tìm là \(\frac{9}{16}\)

So sánh:\(10^{10}\) và \(48.50^5\)

Ta có:

\(10^{10}=10^{2.5}=\left(10^2\right)^5=100^5=\left(2.50\right)^5=2^5.50^5=32.50^5\)

Vì \(32.50^5< 48.50^5\)

\(\Rightarrow10^{10}< 48.50^5\)
