Out of Course question

Answer 1

1^0=1
=>1^0 = 1^1
=>0=1( laws of indices)
second way
0= 100-100/100-100
=>0=(10+10)(10-10)/10(10-10)
=>0=(10-10) get cancelled
=>0=(10+10)/2
=>0=20/2
=>0=2
hence 0=1 & 0=2
Please mark as brainliest.

Answer 2

$HEYA$

1^0 = 1
1^1 = 1

0=1 (LAW OF INDICES)
0 = 100-100/100-100
0=( 10-10)(10+10)/10{10-10}
0 =( 10+10)/10
0 = 20/10
0 = 2
=> 0= 1
=> 0 = 2
