If `(2/3)^x\ \ (3/2)^(2x)=(81)/(16),` . then `x=` 2 (b) 3 (c) 4 (d) 1

Find x' if ((2)/(3))^(xx)x((3)/(2))^(2x)=(81)/(16)

If (3^(5x)x81^(2)x6561)/(3^(2x))=3^(7), then x=3 (b) -3(c)(1)/(3)(d)-(1)/(3)

If x^(3)=(1)/(x^(3))=14, then x-(1)/(x)=5 (b) 4(d)3(d)2

If log_(3){5+4log_(3)(x-1)}=2, then x is equal to 4 (b) 3 (c) 8 (d) log_(2)16

If (16)^(2x+3)=(64)^(x+3), then 4^(2x-2)=64(b)256(c)32(d)512

If 2^(2x-1)+4^(x)=2^(x-(1)/(2))+2^(x+(1)/(2)), then x equals a.(1)/(2) b.(2)/(3) c.1 d.(3)/(2)

int (2x ^ (3) + 3x ^ (2) + 4x + 5) / (2x + 1) dx equls to: (A) (x ^ (3)) / (2) + (x ^ (2)) / (2) +3 (x) / (2) + (7) / (4) ln (2x + 1) + C (B) 5 (x ^ (3)) / (2) + 6 (x) / (2) + (7) / (4) ln (2x + 1) + C (C) 3 (x ^ (3)) / (2) + 3 (x ^ (2)) / (2) + (7 ) / (4) ln (2x + 1) + C (D) (x ^ (2)) / (2) + 3 (x) / (2) + (7) / (4) ln (2x + 1) + C

IF ax^3+bx^2+cx+d = |(x^2,(x-1)^2, (x-2)^2),((x-1)^2 (x-2)^2, (x-3)^2), (x-2)^2, (x-3)^2, (x-4)^2)| , then d= (A) 1 (B) -8 (C) 0 (D) none of these

If log_(x)((9)/(16))=-(1)/(2), then x is equal to a.-(3)/(4) b.(3)/(4) c.(81)/(256)d.(256)/(81)

If 8^(x) = (4)/(2^(x)) then find x A)1 B)2 C) (1)/(2) D) (2)/(3)
