Find the hcf of 12,15 and 20

yawa3891 [41]

HCF of 12 and 15 by Prime Factorization

1. As visible, 12 and 15 have only one common prime factor i.e. 3. Hence, the HCF of 12 and 15 is 3.

2. To find the HCF of 20 and 25, we will find the prime factorization of the given numbers, i.e. 20 = 2 × 2 × 5; 25 = 5 × 5. ⇒ Since 5 is the only common prime factor of 20 and 25. Hence, HCF (20, 25) = 5.

TRUE or FALSE: Every number raised to a negative exponent will have a value smaller than 1. Explain your reasoning.

Sveta_85 [38]

Answer:

<h3><u>Required Answer</u><u>:</u><u>-</u></h3>

Every number raised to a negative exponent will have a value smaller than 1.

This is False statement

<h3><u>Reason</u><u> </u><u>:</u><u>-</u></h3>

It will only be negative if the number is negative with an odd exponent.
what you're actually doing is dividing instead of multiplying.

<h3>For Example:-</h3>

$\sf 4^2=16 \\ But \\ \sf 4^{-2}={\dfrac {1}{16}}$

A drawer contains 4 red socks, 7 white socks, and 11 blue socks. Without looking, you draw out a sock and then draw out a second

Tanya [424]

Total socks = 4 + 7+ 11 = 22
Red = 4
White = 7

P(red, then white) = (4/22)(7/21) = 2/33

Answer: 2/33
