1.)(3/4)^-2
=(4/3)^2
=16/9 ans
2.)1/2(4^-2÷4^-4)
=1/2 {(1/4)^2÷(1/4)^4}
=1/2 (1/16÷1/256)
=1/2 (1/16×256)
4.)given,
volume of the iron =1 m^3
=1×1000=1000mm^3
diameter of the wire=4mm
radius of the wire=4/2 =2mm
a/q
volume of the wire = vol. of iron
=>22/7×r^2×h=1000
=>22/7×2×2×h=1000
=>11.36×h =1000
=>h=88.02mm
