(18)^3.5÷(27)^3.5×6^3.5+2^x then the value of x is ?
TPS:
anirudh, this is not an equation. there is no '=' symbol here. I think you have done some mistake while writing the question. please check it.
(18)^3.5÷(27)^3.5 × 6^3.5 + 2x
no i hadn't but it possible that it is mistake in printing
please don't talk
please
keep silence
actually I have hint that its anweer is 7
answer*
Maybe i am wrong. A user has answered and his answer is 7. So maybe he is correct. Anyway, have a good day!
ok thank-you

can you explain last step that how it comes to 2^7 = 2^x?

(18)^3.5 ÷ (27)^3.5 x 6^3.5 = 2^x
(18)3.5 x 1/(27)^3.5 x 6^3.5 = 2^x
(3²x 2)³°⁵ x 1/(3³)³°⁵ x (2 x 3)³°⁵ = 2^x
3^(2 x 3.5) x 2^3.5 x 1/3^(3 x 3.5) x 2^3.5 x 3^3.5 = 2x
3⁷ x 2³°⁵ x 1/3^¹⁰°⁵ x 2³°⁵ x 3³°⁵ = 2x
2⁷ = 2^x
x = 7
can you explain how in last step it comes to 2^7 = 2^x??
