Answer 1

Answer:

good morning..!!!

Explanation:

1. 121-1=120

120-3=117

117-5=112

112-7=105

105-9=96

96-11=85

85-13=72

72-15=57

57-17=40

40-19=21

21-21=0

for all the other one use 1,3,5,7,9........n. for subtraction..

this was just one of the example..you try for other three!!!

Answer 2

Answer:

$\huge \boxed{121}$

$121-1=0\\120-3=117\\117-5=112\\112 - 7 = 105 \\ 105 - 9 = 96 \\ 96 - 11 = 85 \\ 85 - 13 = 72 \\ 72 - 15 = 57 \\ 57 - 17 = 40 \\ 40 - 19 = 21 \\ 21 - 21 = 0$

$\huge \blue{ {11}^{2} = 121 }$

_____________________

$\huge \boxed{64}$

$64 - 1 = 63 \\ 63 - 3 = 60 \\ 60 - 5 = 55 \\ 55 - 7 = 48 \\ 48 - 9 = 39 \\ 39 - 11 = 28 \\ 28 - 13 = 15 \\ 15 - 15 = 0$

$\huge \red{ {8}^{2} = 64 }$

_____________________

$\huge \boxed{49}$

$49 - 1 = 48 \\ 48 - 3 = 45 \\ 45 - 5 = 40 \\ 40 - 7 = 33 \\ 33 - 9 = 24 \\ 24 - 11 = 13 \\ 13 - 13 = 0$

$\huge \green{ {7}^{2} = 49 }$

Extra related to this:-

Repeated subtraction is a method of subtracting the equal number of items from a larger group. It is also known as division. If the same number is repeatedly subtracted from another larger number until the remainder is zero or a number smaller than the number being subtracted, we can write that in the form of division.

Simple Example:-

Very simple exam we know that

${2}^{2} = 4</p><p>1)4-1=3\\2)3-3=0$

Count the number of times you subract the odd numbers then write the number of times you subracted is the square.

try to do forth example by yourself .So that you can feel easy.
