Jika diketahui x + y = 3, maka nilai dari [{9^(x-2y)} . {2^(2x-y+2)}] / [{3^(x-5y)} . {2^(x-2y+1)}].... Question from @gwenlauren36

izharulhaq78 $\displaystyle \frac{9^{\displaystyle x-2y}\times2^{\displaystyle 2x-y+2}}{3^{\displaystyle x-5y}\times2^{\displaystyle x-2y+1}}=\frac{(3^{\displaystyle 2})^{\displaystyle x-2y}\times2^{\displaystyle 2x-y+2}}{3^{\displaystyle x-5y}\times2^{\displaystyle x-2y+1}}\\\frac{9^{\displaystyle x-2y}\times2^{\displaystyle 2x-y+2}}{3^{\displaystyle x-5y}\times2^{\displaystyle x-2y+1}}=3^{\displaystyle 2x-4y-(x-5y)}2^{\displaystyle 2x-y+2-(x-2y+1)}$
$\displaystyle \frac{9^{\displaystyle x-2y}\times2^{\displaystyle 2x-y+2}}{3^{\displaystyle x-5y}\times2^{\displaystyle x-2y+1}}=3^{\displaystyle 2x-4y-x+5y}2^{\displaystyle 2x-y+2-x+2y-1}\\\frac{9^{\displaystyle x-2y}\times2^{\displaystyle 2x-y+2}}{3^{\displaystyle x-5y}\times2^{\displaystyle x-2y+1}}=3^{\displaystyle x+y}\times2^{\displaystyle x+y+1}$
$\displaystyle \frac{9^{\displaystyle x-2y}\times2^{\displaystyle 2x-y+2}}{3^{\displaystyle x-5y}\times2^{\displaystyle x-2y+1}}=3^{\displaystyle 3}\times2^{\displaystyle 3+1}\\\frac{9^{\displaystyle x-2y}\times2^{\displaystyle 2x-y+2}}{3^{\displaystyle x-5y}\times2^{\displaystyle x-2y+1}}=27\times2^{\displaystyle 4}\\\frac{9^{\displaystyle x-2y}\times2^{\displaystyle 2x-y+2}}{3^{\displaystyle x-5y}\times2^{\displaystyle x-2y+1}}=27\times16$
$\displaystyle \boxed{\boxed{\frac{9^{\displaystyle x-2y}\times2^{\displaystyle 2x-y+2}}{3^{\displaystyle x-5y}\times2^{\displaystyle x-2y+1}}=432}}$

Bantuin yg nomor 11 dan 12 dongg pleasee makasi banyakk

No.1 : (9^x + 9^-x) = 98, maka nilai (3^x + 3^-x) = ... no.2 : x+y=1 dan x^3 + y^3 = 49, maka x^2 + y^2 = ... makasii

[{(0,09^(3/2)).(x-3)} / (0,3^(4x+1))] = 1 nilai x yg memenuhi persamaan adalah ... (no.2)

[ {(5^(1/2) + 2 )^6} - {(5^(1/2) -2 )^6} ] / 8.(5^(1/2)) = ... help me again please? thankyou very much god will always bless ya. ^^ * yg hari itu salah soal

Bantuin yg nomor 18 dong, beneran gak ngertii, makasii x gbu❤

[ {(5^(1/2) + 2 )^6} - {(5^(1/2) -2 )^6} ] / 80^(1/2) = ... help me again please? thankyou very much god will always bless ya. ^^

[{ 7^x + 2.(7^x) + 3.(7^x) + 4.(7^x) + ... + 49.(7^x) } / 25 ] = 343 nilai x yang memenuhi persamaan adalah ... help please, thnks x

Cara cepat mengerjakan : (48 . 27 . 35 . 175 . 245) ^(1/2) adalah .. thankyouu

Jika a^(3/2) = b^(-3/2) . c^(3/4), maka c dinyatakan dalam a dan b adalah... help please? :) thanks
