Write a pythogorean triplet whose smallest number is 20?

vladimir2022 [97]

Answer:

20,21,29 or 20, 99 and 101.

Step-by-step explanation:

$a^{2} +b^{2} =c^{2}$

$20^{2} +21^{2} =29^{2}$

$400+441=841$

OR:

$a^{2} +b^{2} =c^{2}$

$20^{2} + 99^{2} = 101^{2}$

$400+9801=10201$

Answer:

y^7

Step-by-step explanation:

y^3 . y^5 . y^-2 . y

= y^3 . y^5 . y^-2 . y^1

= y^( 3 + 5 - 2 + 1 )

= y^( 3 + 5 + 1 - 2 )

= y^( 9 - 2 )

= y^7
