a) `4(m+3)=18`, b) `-2(x+3)=8`

Solve (a) 4(m+3)=18 (b) -2(x+3)=5

Solve (a) 4(m+3)=18(b)-2(x+3)=5

Simplify the following (i) (3a^4b^3)(18 a^3b^5) (ii) (3a^7b^6)/(18 a^6b^8) ((-2a^2)/(b^3))^3

4m+3n=18.3m-2n=5

Calculate the extent of hydrolysis and the pH of 0.02 M CH_3COONH_4. [K_b (NH_3)=1.8×10^(−5) , K_a (CH 3COOH)=1.8×10^(−5) ]

The pair of simultaneous equations from the following is…………………(1) 2x+2y=7 (2) 4x+3z=9 (3) 3y+4z=8 (4)3z+9x=18 a)1 and 2 b)2 and 3 c)3 and 4 d)2 and 4

If 4^(x+3)=112+8xx4^(x) , find (18x)^(3x)

(m-1)/(m-4)=(2m-3)/(3m-8)

If x+2 and x-1 are the factors of x^3+10 x^2+m x+n, then the values of m and n are respectively=? (a) 5 and -3 (b) 17 and -8 (c) 7 and -18 (d) 23 and -19
