उत्तर

y = `10^("x"^"x") + 10^("x"^10) + 10^(10^"x")`

Differentiating both sides w.r.t.x, we get

`"dy"/"dx" = "d"/"dx" (10^("x"^"x") + 10^("x"^10) + 10^(10^"x"))`

`= "d"/"dx" (10^("x"^"x")) + "d"/"dx" (10^("x"^10)) + "d"/"dx" (10^(10^"x"))`

∴ `"dy"/"dx" = 10^("x"^"x") * log 10 * "d"/"dx" ("x"^"x") + 10^("x"^10) * log 10 * "d"/"dx" ("x"^10) + 10^(10^"x") * log 10 * "d"/"dx" (10^"x")`

`= 10^("x"^"x") * log 10 * "x"^"x"(1 + log "x") + 10^("x"^10) * log 10 * 10 "x"^9 + 10^(10^"x") * log 10 * 10^"x" log 10`

∴ `"dy"/"dx" = 10^("x"^"x") * "x"^"x" * log 10(1 + log "x") + 10^("x"^10) * 10 "x"^9 * log 10 + 10^(10^"x") * 10^"x" (log 10)^2`

Fill in the blank.

If x = t log t and y = tt, then `"dy"/"dx"` = ____

Choose the correct alternative:

State whether the following statement is True or False:

Find `("d"y)/("d"x)`, if y = `x^(x^x)`


Find `("d"y)/("d"x)`, if y = `root(3)(((3x - 1))/((2x + 3)(5 - x)^2)`


Find `("d"y)/("d"x)`, if y = x(x) + 20(x) 

Solution: Let y = x(x) + 20(x) 

Let u = `x^square` and v = `square^x`

∴ y = u + v

Diff. w.r.to x, we get

`("d"y)/("d"x) = square/("d"x) + "dv"/square`   .....(i)

Now, u = xx

Taking log on both sides, we get

log u = x × log x

Diff. w.r.to x,

`1/"u"*"du"/("d"x) = x xx 1/square + log x xx square`

∴ `"du"/("d"x)` = u(1 + log x)

∴ `"du"/("d"x) = x^x (1 +  square)`    .....(ii)

Now, v = 20x

Diff.w.r.to x, we get

`"dv"/("d"x") = 20^square*log(20)`     .....(iii)

Substituting equations (ii) and (iii) in equation (i), we get

`("d"y)/("d"x)` = xx(1 + log x) + 20x.log(20)
