How many 2 digit numbers do not use the numeral 5?

hram777 [196]

Alot! So the ones with 5 like 15,25,35,45,55,65,75,85,95! Each one inbetween is 10 so it would be 80

use the fact that 10^3 = 2^10 to mentally find a vaule of n for which 2^n > 10^50 & 10^n > 2^300

Rudiy27

$2^n>10^{50}=10^{3\cdot16+2}=10^2(10^3)^{16}=10^2(2^{10})^{16}=5^22^{162}$
$2^{n-162}>25$

The least power of 2 that exceeds 25 is $2^5=32$ , so we have

$2^{n-162}=2^N>25\implies N=5\implies n-162=5\implies n=167$

- - -

$10^n>2^{300}=(2^{10})^{30}=(10^3)^{30}=10^{90}$

The least integer $n$ that satisfies this inequality would clearly be $n=91$ .

Solve for x in the diagram.

Kazeer [188]

It is a right triangle so,

a² + b² = x²
9² + 12² = x²
225 = x²
√225 = x
15 = x

Hope this helps :)
