Simplify
`t(3t+2)-(5t -4) +7`

Remove the brackets and simplify : 3(3s - 2t) - 4 (s+2t)

Simplify: (i) ((2^5)2 xx 7^3)/(8^3 xx 7) (ii) (25 xx 5^2 xx t^8)/(10^3 xx t^4)

Simplify. (i) (25 xx t^(-4))/(5^3 xx 10 xx t^(-8)) (t != 0) (ii) (3^(-5) xx 10^(-5) xx 125)/(5^(-7) xx 6^(-5))

Simplify the following (t - 2) (t+3)

Solve : (3t-2)/4 - (2t+3)/3 = 2/3 - t

solve the equation . (3 t - 2)/(4 ) - (2 t + 3)/(3) = 2/3 - t

Simplify each of the following expressions: 4s t\ (s-t)-6s^2(t-t^2)-3t^2(2s^2-s)+2s t(s-t)

The distance covered by an object (in meter) is given by s=8 t^(3)-7t^(2)+5t Find its speed at t = 2 s.

Simplify and solve the linear equations. 3(t-3)=5(2t+1)

Power applied to a particle varies with time as P=(4t^(3)-5t+2) watt, where t is in second. Find the change its K.F. between time t = 2 and t = 4 sec.
