Simplify (4^2)*(2^3)*16

Indice rules are fundamental in answering this question 1) (a b )(a c ) = a (b+c) 2) (a b )/(a c ) = a (b-c) 3) (a b ) c = a (b c) 4) a (-b) = 1/(a b ) 5) a 0 = 1 We can simplify 4 2 to (2 2 ) 2 and using ru...

What provides the centripetal force on a satellite and what are the factors that determine the size of the centripetal force on the satellite

Centripetal Force = (mv^2)/r The centripetal force must always act towards the centre of the circle in which the satellite is travelling. Therefore it is a attractive force from the Earth and hence gravitati...

Solve the equation 3x^2/3 + x^1/3 − 2 = 0

Let u = x^1/3 The equation can therefore be written as: 3u^2+u-2=0 This can be factorised to: (3u-2)(u+1)+0 Therefore: u = 2/3 or u = -1 OR x^1/3 = 2/3 or x^1/3 = -1 So: x = (2/3)^3 or x = (-1)^3 x = 8/27 or...
