The value of `1^(1-1)` is
`(a) 2`
`(b) -1`
`(c) 0`
`(d) 1`

If (a)/(b)+(b)/(a)=2, then the value of (a-b) is (a) 1 (b) 2(c)-1 (d) 0

Find the value of (( 2^0 + 1)/ 5^0 ) is ( a ) 2 ( b ) 1 ( c ) ( 2/5 ) ( d ) ( 3/5 )

If a+ b+c + d = 4 then the value of 1/((1-a) (1-b) (1-c)) + 1/((1-b) (1-c) (1-d)) + 1/((1-c)(1-d)(1-a)) + 1/((1-d)(1-a) (1-b)) is

Find the value of ( 5^0 + 3^0 ) - 2 ( A ) -1 ( B ) 0 ( C ) 1 ( D ) 2

Find the value of ( -1/2 )^5 / ( -1/2 )^4 ÷ ( ( -1/8 ) )/( (-1/4 ) ) is ( A ) 2 ( B ) 0 ( C ) 1 ( D ) -1

Find the value of ( ( 1/3 )^(-2) + ( 1/4 )^(-2) ) ÷ ( 1/5 )^(-2) ( a ) 0 ( b ) -1 ( c ) 1 ( d ) 7/5
