If `[{((1)/(7^(2)))^(-2)}^(-1//3)]^(1//4)=7^(m)` , then m= _____.

[{((1)/(7^(2)))^(-2)}^((1)/(3))]^((1)/(4))=7^(m), is -(1)/(3)(b)(1)/(4)(c)-3(d)2

Find the value of [ { ( 1/7^2 )^-2 }^(-1/3 ) ]^(-1/4 )

If (2+(1)/(3(4)/(5)))/(2+(1)/(3+(1)/(4)))=x, then the value of x is (1)/(7) (b) (3)/(7)(c)1(d)(8)/(7)

(7)/(8)-(3)/(4)+(1)/(2)=(7-3+1)/(8)=

(7)/(8)+(3)/(4)((1)/(2))(2)/(3)-(1)/(3))

If 2^(-m)xx(1)/(2^(m))=(1)/(4) then (1)/(14)[(4^(m))^(1//2)+((1)/(5^(m)))^(-1)] =_______

((3^(-1)7^(2))/(3^(3)7^(-4)))/((3^(3)7^(-5))/(2^(-2)7^(3)))

If for 1lemlen,f(m,n)=C_(0)-C_(1)+C_(2)-....+(-1)^(m-1)*C_(m-1) , then f(7,8) is

Solve : (i) 2^((2)/(3))*2^((1)/(4)) (ii) ((1)/(3^(3)))^(7) (iii) (11^((1)/(2)))/(11^((1)/(4))) (iv) 7^((1)/(2))*8^((1)/(2))

7(1)/(2)-((8)/(11)xx7(1)/(3))-:(3(1)/(2)-2(1)/(4))
