a^x=b^y=c^z

apply log on all SIDES

and let it EQUALS to k

HENCE , xloga=ylogb=zlogc=k

loga=k/x, logb=k/y, logc=k/z

substitute in loga*logc/(logb)^2

15.	Solving equation x2+8x=-15 by completing square,find third term
Answer» Equation : x² + 8X = - 15 Adding the half of coefficient of ' X ' on both sides we GET, x² + 8x + 4 = - 15 + 4 => ( x + 4 )² = - 11 Taking root on both sides we get, => x + 4 = √ - 11 √ - 11 is not possible as it is an unreal NUMBER . Hence the equation cannot be solved further. Hence the equation will have imaginary roots.

Solving equation x2+8x=-15 by completing square,find third term

Answer»

Equation : x² + 8X = - 15

Adding the half of coefficient of ' X ' on both sides we GET,

x² + 8x + 4 = - 15 + 4

=> ( x + 4 )² = - 11

Taking root on both sides we get,

=> x + 4 = √ - 11

√ - 11 is not possible as it is an unreal NUMBER . Hence the equation cannot be solved further.

Hence the equation will have imaginary roots.

I spent 3/5 of my money and still rs.1000 left. what was the amount i had?

Answer»

Hey friend,

_____________________________________________________________

Question: I spent 3/5 of my money and still RS.1000 left. What was the AMOUNT I had?

Solution:

Let the total money be x.

³/₅ x of money is spent {GIVEN}

Amount of money left = Rs. 1000 {Given}

Fraction of money left = x - ³/₅ x

= ²/₅ x

So, ²ˣ/₅ = 1000

x = ¹⁰⁰⁰ *⁵/₂

x = 2500

Ans: Rs. 2500 was the total amount of money.
